Brave's entire business model is pretty explicitly about selling your data for targeted advertisements. I find it unreasonable to even suggest Brave as an alternative if your concern with Mozilla is the "selling your data" language.
Also re MitM'ing for crypto mining: I was never in favor of pushing Brendan out of Mozilla for being a supposed right-wing nut, but I am not surprised either to see that, given free reign, he _is_ a right-wing nut.
There's even more FUD about Brave than there is about Mozilla. Brave downloads all ads and decides on what it shows you locally; the data never leaves your machine. You also have to opt-in into this system, it is disabled by default.
Maybe, it's also the time I uninstalled it. Maybe it's a completely different company now, or maybe it's the same one. Briefly checking controversies on Wikipedia and since then they've installed promoted VPNS, and pretending to be Tom Scott to solicit donations: https://web.archive.org/web/20181224011529/https://twitter.c...
What we do catch makes me decide how much to trust companies to do what we don't see.
Mozilla becoming untrustworthy doesn't make another company trustworthy.
That sounds like the Brave Rewards system that's opt-in afaik. It's a grift, but so far one that at least provides a decent user experience while being somewhere in the ballpark of just as bad as Firefox could be extrapolated to become in the near future.
Firefox's sponsored startpage blocks and search suggestions are opt-out features. If you don't trust an opt-in system, you should trust an opt-out one even less.
If it's opt-in now that's an improvement. When I was using Brave around 2018ish it appeared as part of an update. Companies trying to 'redefine' advertising always make me suspicious - it's similar to what Mozilla has been trying to do over the last couple of years.
I have some shamefully bloated webpages and some rather low end computes. I don't know why or how and realize it is highly anecdotal. Just sharing my surprise. I don't have any extensions. (if you do add things to chrome that are native in brave I imagine it to work slower) Perhaps it is my limited ram that holds back (the more memory hungry) chrome. Not sure how regularly calling home affects chrome.
