How many times PC games / software store vanished without a trance in a known history while breaking all previously downloaded games / software? Yeah services

How many times PC games / software store vanished without a trance in a known history while breaking all previously downloaded games / software? Yeah services do come and go, but they are mostly just distributors and not product owners. Any sane software developer will always gonna give you a key for software you previously bought, but for the new platform if something like that happens. On other side Apple do push developers off their platform all the time and old apps getting abandoned all the time when API breaking and App Store no longer sell the app.
