If offline mode makes it to release, it will be bricked within 3 months after they get their cash grab.
What do you mean exactly? I kind of plan to get the game but o ly if it's playable offline (fully). If they can still prevent me from launching it, I'm not interested.
Just stating that, in fact, the "purchaser" doesn't own games anymore and they have the right and ability to do what they want after they have your (the purchasers) money.
TLDR: They can legally do whatever they want at any time which includes flipping a switch to kill the offline mode.
I doubt it
