It is not propaganda as it is factual information. If you believe this is 4D chess from Google to manipulate us to dislike Firefox you are out of your mind. https://github.com/mozilla/bedrock/commit/d459addab846d8144b61939b7f4310eb80c5470e this is an actual commit made by mozilla. It was not made by Google.

Changes include:

• Removing "we don't sell access to your data". Curiously this change is only for the TOU. Presumable because that is legally binding. Idk where the "else" branch is displayed though.
• Removing this question from FAQ: "Does Firefox sell your personal data? Nope. Never has, never will (...). That's a promise"
• Remove another mention in the TOU "and we don't sell your personal data". That again was not removed from the "else" branch

That to me indicates one of the following:

• They have started selling data.
• They plan on selling data in the near future.
• They don't feel confident that they can keep that promise forever. That is, they see a future where they sell data.

I don't like either of those alternatives.

I don't know if they are able to sell the data you mentioned. Because I'm not in the enshittification minds of giant American corporations. 20 years ago people would laugh at the idea of buying data about the screen size of a user. But now they do, and use it for fingerprinting. If recent history has shown anything is that most data has some kind of value. And giant corporations will find their way to use that data against users.

I've seen way too many companies that were supposed to be the cool kids and were doing everything morally enshittify. There's no reason to believe Mozilla is going to be different. They're showing the same signs.
