I was their user since version 5 or 6 (this was before everyone started the crazy version system, back them they released a major version about once a year).
The biggest things that I loved about the browser you couldn't get by extension, they could do many things because they could directly update the engine.
Now learning that they are owned by PRC there's even less reasons for me to use it.
Opera could have done a lot of good if they would open sourced their old browser (kind of line what Netscape did). Someone leaked the original source code, but because it was leaked and not officially published, no one wants to touch it. Anyway now it's too late, because it's way behind the current browsers.
All the reasons (privacy/spying, government unaccountability, etc.) that would make basing a tech company in the US bad are worse in China.
It does seem, though, many are (seemingly in bad faith) increasingly conflating criticism and scepticism of the Chinese government with racial or ethnic animosity. It is almost identical to how discussions surrounding the Israeli government are conflated (seemingly in bad faith) with anti-Semitism.

America does bad too, but we can't act like this state is any better. Some of the things they're doing to play catch up are appalling.
