I'm aware that it's not FB's fault about the game developers moving on 😅 and it was a "risk" and still is when making use of those platforms owned by others.
And I get what you mean about the power social media companies have over "our" accounts... When we open an account we kind of sign away our rights to the content. Luckily I haven't done much on those platforms the last couple of years, but I do know entrepreneurs making use of those social media channels to promote their businesses and services and even the people who use it for private purposes; to all of them a shutting down or "silencing" from the company would be a major loss.
