A very interesting discussion, indeed. My main point in it would be: What is the real danger in the Chinese ownership? Most of our devices were somehow made in China, a lot of software in cars e.g. are built on Chinese architecture.
I guess, that being majority owned by a Chinese consortium doesn‘t mean fully controlled either. I guess that open source software like Firefox may win on the privacy side of things. But corpos normally tend to use software made by the likes of Microsoft or Alphabet.
And doesn‘t Brave come with its own bag filled with questionable issues?
