Huh, you're absolutely right, I haven't noticed that. Now, to be fair the text without the text isn't that much different but it does exclude the explicit promise not to sell data. The text shown without the flag set – and is currently shown on the Firefox website – states:

"... we believe the internet is for people, not profit. You’re in control over who sees your search and browsing history. All that and exceptional performance too."

So the sentence "Unlike other companies, we don’t sell access to your data." Is missing. So yeah, i agree, not great. But we'll see what actually happens.

To be clear, my intention isn't to defend Mozzila, for example I really don't like their privacy policy allows them to "collect technical and interaction data, such as the position, size, views and clicks on New Tab content or ads, to understand how people are interacting with our content and to personalize future content, including sponsored content." I just don't like drawing wide-sweeping conclusions based on things like wording changes.

Another thing: their acceptable use policy straight up forbids viewing pornography or graphic violence. No nuance or exceptions.

The new TOS says nothing about pornography nor does the general Mozzila services acceptable use policy:

• [https://www.mozilla.org/en-US/about/legal/terms/firefox/](Firefox TOS)
• [https://www.mozilla.org/en-US/about/legal/acceptable-use/](Mozzila acceptable use policy)

The original text talks about not selling data an the new text talks about not selling data. I don't really understand what you're trying to say, the previous promise also doesn't say anything about what you're talking about.

This seems out of context. The same git commit that removes the paragraph OP pointed out also adds the following text:

"We believe the internet is for people, not profit. Unlike other companies, we don’t sell access to your data. You’re in control over who sees your search and browsing history. All that and exceptional performance too."

To me that seems more like a re-wording than a fundamental change.

Edit: I somewhat misread the commit, as @[email protected] pointed out below.
