It's also about making sure you can't sue them, even if they did something wrong, even if they did it on purpose, even if they knew it was wrong when they did it.
Instead you must agree to "binding arbitration", so that if you lose they get to learn what strategy works against customers, and if you win they get to learn what strategy doesn't work against customers (but in any case the details cannot be shared with other customers).
Also, you can never participate in a class action suit, so even if they did do something wrong, on purpose, and you convinced a -judge- arbiter, you just get the $12 judgment, or whatever the value is of your actual damages. The corporation can keep the $12 they stole from each of their millions of other customers, who didn't also start arbitration.
It is shocking that it is even legal
Yes, the game supports split screen local co-op on consoles and even on PC.
You can play through the first 2/3rds of the game in split screen with no trouble. However, in my experience it gets unstable in act 3 on Xbox Series X (probably also on PS5). Presumably it is something to do with the limited memory on consoles, so if your PC has great specs it should work there.
They are planning an update due next month which is supposed to address the crashing, but it remains to be seen.
I think currently the best experience on consoles is to have two copies of the game on separate consoles.
The patch 7 update also will supposedly add cross platform multiplayer, so you could have one player on console and one on PC, since you probably don't have two Xboxes, but again, it remains to be seen
