HiTech also requires an account to play Aces High. Logging in to Oculus with a Facebook account is no big deal, it will provide features that outweigh any security risk. I already have a Facebook account with enough pictures to develop a deepfake of myself, they aren't going to be watching me play video games just because they are a big company.
I just ordered the Oculus Quest 2 for my kids, I was going to go with the Rift S, but it didnt seem to have any large benefits over the Quest, and the Quest can be used stand alone and wireless. Just takes a USB-C cable to play some PC games. I used to have the original Rift and used it for Aces High. I enjoyed the flying experience with it, but was much worse in combat. I thought my depth perception was way off and I wasnt hitting targets even though it looked like I should be. My situational awareness was actually much lower than when I use hat keys on a joystick.
Facebook sells you, HiTech does not. Facebook has had security breaches that exposed millions of users. If you are fine with putting your family out there, be my guest.
AH is the only reason I thought I would get VR. With recent changes to the game, I am starting to lose interest in it. Really never thought I would say that.
