Somehow I highly doubt that a small game company is going to run a "huge network of interconnected cloud services". I've also yet to find a small game company running their own big online multiplayer game.

Your argument still doesn't hold, sorry. The law won't apply retroactively so the existing games can be killed. However, if the law passes, the EOL plan just becomes another product requirement you have to plan for. So you won't "rewrite" the server code, you write it to comply in the first place.

This was also the excuse people gave for GDPR and California's privacy law and everybody got forced into complying after the date of validity. Simply having an "excuse" of money loss due to engineering your game user-hostile in the first place (especially after the law became valid) isn't a good argument. It will have some preparation time and if you didn't plan for it, it is your fault.
