As a non-dev, I can't say if that's standard, but it doesn't sound like good practice. Regardless, just like the woman said, GDPR was thought to have mAssIVe cOsTs upon development and business, but in the end companies dealt with it. Companies with insufficient preparation or unwilling to plan to leave the game in a playable state, will have to factor in the costs of not complying.

This issue is about consumer rights and if you're for "what you buy is what you own", then being against rendering games unplayable after purchase should be logical.
