GPL/AGPL/LGPL is the way to go for business. There are many dual-licensing success stories using GPL/AGPL, both large and small: Qt, iText, Grafana, Loki, Tempo, Mattermost, Cal.com, Baserow, and even MongoDB originally.
Qt is an especially interesting case because KDE and the Qt Company have a written contract. Qt can't just switch licenses. They have retreated from every voluntary contribution to open source, but the contract binds them and they can't do anything to it unless they do complete rewrite from scratch.
What does bother me is when the projects pivot to claiming that users now have a moral obligation to financially support the project. There is a kind of dishonesty in this move.
It's not that a successful project "should be free", it's that its success depended on it being free. If they had said all along that they'd eventually ask users to pay, that would be honest... but then they wouldn't have seen much of that adoption in the first place.
I suspect this is also the case for PHP though.
Likewise, users are free to continue using open source software without payment or donation, to fork the project, etc. If anyone tries to shame them for this, they should pay no mind.
Also it gets less fun when people start making demands of you and you have to deal with taxes and all the unfun stuff.
It only bothers me when they try to claim their new license is open source or use misleading language when it isn't. Which seems to be what 90% companies doing that do.
People can do whatever they want with their intellectual property as long as they aren't lying about it.
Until very recently, big tech pumped untold millions of dollars into obliterating FLOSS altogether, calling it a cancer that will destroy any enterprise it touches.
But if it was true: In the 90s, millions of small businesses around the world used FLOSS to host websites and offer services over the internet. That was decidedly not the route big enterprises wanted to go. They wanted to push through big standards through ITU et al, build giant, patented moats, and host it all on big mainframes with huge Oracle databases.
Even today, there exist small to medium businesses in the hosting and shopware space, and they can only do that because big tech could not push them out of that space because FLOSS protected them.
