If something is free, you are the product. The more info you give away, the more money the company makes. Do you see a cut of that money? No.
I don't use windows or, when I did, sign in to a windows account.
I wouldn't/won't buy a quest because it wants a Facebook log in, which I don't have, because Facebook makes money from me, none of which I see. Unfortunately, not all data can be avoided been given away, but I avoid It where I can.
Don't reply to me after this as I'm done with the subject until next time. If you think this is not a big deal, then that's ok take "120 seconds" to sign up for an account and I hope you continue to enjoy your game.
Remember that death comes in a thousand cuts and the frog boils slowly.
