Pretty much every year I'm getting warnings from Apple or Google, or 3rd party SDKs, that unless I make sure to update libraries, or comply with a new rule, they are going to take down the game.
One of the latest rules was some sort of a digital services act (again another regulation) that made it very difficult for indie devs not to share their personal address and phone numbers.
In principle, as long as _you_ are not blocking using the binary on hardware that supports (i.e. a player already has it installed on an old phone), you're in the clear.
SKG is explicitly _not_ advocating for lifetime support, compatibility with new devices, etc
Being bootstrapped with no investors, there's no extra resources, and no financial benefit in making sure that the app can function well even with these 3rd party services, servers etc. not working.
Yeah, it's a good point, the law that may result from parliament does need to be clear on where the line is drawn.
Personally, I would expect singleplayer and LAN to work at EOL
Edit: on 3rd party libraries & services, I would expect that such vendors would need to make their software compliant for their customers after any law change on this front. No one is gonna buy GameLift if it's a legal liability for their EOL plan
