If you are worried about privacy, don’t look at the windows 10 user license... or the android license etc..
Reality is, if you want privacy, you have to completely disconnect... either that or go buy an old 8 bit machine with a network card, and do whatever you need to do online that way.
Maybe something like a c64/128 with a 64nic+ card... of course you better be able to code, because I am not aware of any text web browsers for them, let alone graphical ones.... let alone ones that support javascript, but you’ll not have to worry as much about data collection from your OS.
Well, at least they have to dig a little bit. It’s not all sitting under one domain ready for the taking.
