Yeah I keep pushing for join-lemmy.org to buy ads on Google and Bing.

They do not. Your use of the software, with software you “control” (edge cases of cloud compute, etc.) does not require you to grant a license to the software.

I refuted most of these points on this user’s post.

This is absolutely abnormal. No browser should require a license to my own data unless they plan on doing something with it.

No other FOSS includes this language and I would argue that Firefox executable is no longer FOSS. It’s now source available.
