“My wife and I use Opera as the default browser. Any idea whose side Opera’s creators are on?”
I like Opera, but it is based on Chrome, and I think is now owned by China.
My browser of choice would be Brave, since it was created deliberately by Brendan Eich (after he was fired from Mozilla, which he also helped create, for donating to an anti-same-sex marriage referendum) to preserve privacy.
Brave is an excellent, well thought-out browser: easy to use and protective of the user. It automatically eliminates most ads, annoy-ware and ensures user privacy without the need for worrying about external add-ons. I am quite impressed with it.
