Well essentially there are 3 browsers. Chrome / Firefox / Safari. Everything is a version of these three (besides niche browsers, like I think KDE might have their own browser)

What I mean by independent is Firefox is the only one not owned by a massive international corporation. I would say the only open source one but Chromium is technically open source.

You can for example download “ungoogled chromium” which is a Chromium fork that removes the Google telemetry

How is Apple “independent”? You’re just trading one mega corporation for another.

It’s not Chromium specifically, but it has basically the same issues.
