Because here’s the thing, lawyers are super expensive and these corporations have in house lawyers for handling anyone that wants to sue. They’ll happily argue the validity of the EULA because they know just getting through the pretrial phase will cost you tens if not hundreds of thousands of dollars.
Corporations have weaponized this fact at every chance they get.
It’s the exact same reason why companies in California and other states make employees sign noncompetes, even though they are explicitly unenforceable. It’s so the company can financially punish you even if you are in the right.
