I'm not sure why this was downvoted. US companies have been caught regularly adding backdoors to products sold abroad (from the top of my head, I seem to remember IBM admitting the charges, Microsoft being caught red-handed, etc.)
Last November, Emmanuel Macron gave a big speech about the fact that the EU cannot rely anymore on the US as an ally for cyberdefense, because the US spent so much effort spying on the EU (and regularly getting caught) that it was not even nearly possible.
So yeah, I trust US companies about as much as Chinese companies, which is not much.
Not like there's a lack of open source web browsers. Why go specifically for the closed source Chinese-owned browser that asks for your crypto keys and provides a "free" "VPN"?
