It wasn't righteous, it was over money (FIFA asking for too much).
> why don't they organise a football world cup instead
Because FIFA is the organising body of football, all regional (UEFA, CONCACAF, etc.) and country Football Associations are under FIFA's jurisdiction (and are members of FIFA). Countries couldn't participate in a rival event even if they wanted to, because many of the smaller association basically only exist on FIFA subsidies, and of course there are exclusivity deals. And i doubt many countries and players would prefer the glory of the "EA Cup". The World Cup has never been about money, and the prize pool is already significant.
As a former-kid who had his own dreams (Scotland winning the World Cup) which have had to be progressively scaled back as I grew up (Scotland qualifying for the World Cup) I sympathise, and I hope your Arsenal pal gets to see the tournament they dream of :)
EA dumping FIFA is a good thing to kickstart the mere idea of competition against FIFA's monopoly (and by extension continental bodies), but any actionable outcome is still decades away.
Do all the manufacturers of sports clothing, shoes, balls, goal posts, etc. have deals with FIFA? Yes
Does FIFA use bribes and any means necessary to prevent anyone from disturbing their racket schemes? Yes
Don’t forget you’re dealing with a lot of very powerful and dangerous people here that make really big money, are deeply intertwined with governments, and have a history of doing anything it takes to earn more money. You’re not going to cut them out of the deal, that simply won’t happen.

FIFA will have a relationship with sponsors of FIFA events (the dozens of brands you see during the World Cup or the Club World Cup) and will select who provides the official ball during these events (usually Adidas) or who makes FIFA-branded merch (lame stuff, relatively small market). But each individual player chooses their own boots + equipment, each national team or club negotiates their own sponsors and kit providers. At Qatar you'll see a wide variety of them - Nike, Adidas, Puma, Hummel, Marathon, Majid, Le Coq Sportif, Kappa, New Balance - FIFA weren't involved in the selection of any of them. And I'm not sure what to say about the goal posts - they'll just be whatever is already in the stadiums in use at any given World Cup.
FIFA is a corrupt enough organization, we don't need to pretend they're also some sinister dictator controlling every level of the global game. Not least because it lets the different confederations and national football associations off the hook for their own mixtures of incompetence and corruption.
However, this is flat our wrong:
> FIFA isn’t involved in regulating the confederations or the members or the clubs
Of course it is. It makes the rules that are implemented by the federations (stuff like 5 subs, the new loan regulations), and it also is the one providing the main funding for the majority of smaller football association (so even if it didn't have any de jure power over them, and it absolutely does, it would have still had de facto power with financing).
No this is flat out wrong, since the laws of the game are governed by IFAB, of which FIFA is a member alongside the Football Associations of England, Scotland, Wales and Northern Ireland. And even then it seems they're flexible in some regards - for example the Scottish FA permitted five subtitutes before IFAB updated the laws and the English FA had a similar trial in the past permitting four subs - both have fiddled with extra stuff like VAR.
I'll grant that FIFA have brought in restrictions on international loan signings - though that's hardly controlling the game the way the original comment implied
I think you're mixing up two things:
1. domestic club competitions - Serie A in Italy, the Bundesliga in Germany, The Premier League in England etc - where players have contracts with clubs and where the most successful teams in each league will compete things like the Champions League.
2. the national game - where country-level football associations select teams based on various national eligibility criteria to compete with other countries in continental competitions (European Championship, CONCACAF Cup etc) and the World Cup.
FIFA are not really involved with #1, it is primarily concerned with the nation-level competitions. It does have a club-level competition between the winner of each confederations' Champions League equivalent, but only the non-European participants really care about that. Additionally, players can and do "just walk" at the national level - some choose not to play either because they don't want to be injured playing for their country in a 9-0 victory over San Marino when their domestic club is in a tight race for the title or they're on a Champions League run. Players also refuse to play for personal reasons - like due to a falling out with a coach (Roy Keane for Ireland in 2002) or with an association (like Duncan Ferguson for Scotland in the '90s). So they know they can refuse to play, but they continue to do so.
There is not a snowball's chance in hell that an alternative World Cup would gain any sort of traction at all. Fans would be dismissive and the various national football associations would not take it seriously either. Additionally, the footballing calendar is already quite full so you couldn't run it in parallel with the existing tournaments, meaning that you couldn't slowly develop and grow the competition gradually, you'd need to replace the world cup from day one.
As shitty as FIFA are, they're here to stay.
