The data Ubuntu “steals” is missing the forest for the trees. Signing into Windows or onto your Macbook hands over more data than Canonical will get from you in years.
Unless you’ve been daily driving Tails for the past decade, you’re looking for the wrong battle.
“Look, these people over there killed millions, so isn’t it OK to kill a couple of people?”
“Hey we can either support the group that killed millions, or support the group that killed a couple people. Or we can go live in a cave in the mountains, realize our beliefs are too difficult, then go back to the group that killed millions.”
OP already runs Linux so that’s fine, but people constantly push the most insane privacy beliefs to newcomers and they end up giving up and going back to Windows. Stop letting perfect be the enemy of good - Canonical has done significantly more for privacy (“to stop killing people”, in your analogy) than any of us shitposters.
Ubuntu ist awesome. I run arch btw
