Others have explained why Chinese ownership of Opera might be bad.
I suggest you try the Vivaldi browser which is made by a company started by the co-founder & CEO of the original Opera. Basically builds upon the heritage and philosophy of the original Opera. Extremely customizable, tracker and ad blocking built in along with speed dials, gestures, UI customization of just about everything.
Has desktop for all platforms including Linux, and mobile for Android and iOS with sync (not going through Google) for all platforms.
Optional email, calendar, Mastodon and RSS clients in the desktop versions. Optional email account and Mastodon account accessible from any standard client and the Web, or via their desktop.
Not fully open source (nor is Opera) and built on the same open source Chromium base as Opera, Brave, Chrome, but seriously de-Googleized and does not use the Chromium UI. Will continue to support ad blocking even after Google/Chromium removal of the interfaces for ad blocking extensions. Yet desktop versions do allow installation of extensions from the Chrome/Chromium extension store.
Edit: fix link and some grammar
I'm afraid that my country the US is entering a dictatorship similar to the 1973-85 dictadura in Uruguay. Even about 40 years later, when I (stupidly) left there, I could see the political and social PTSD from it. Along with Uruguayans being "never again with that horror" from there successful transition to one of the strongest democracies in the Americas.
The big difference is, instead of being a "civic-military" dictatorship, the US is beginning a "civic-techbro" dictatorship.
The military will follow along later. Much of the enlisted, non-officer troops are pro-Trump. Even some officers are.
