It's disingenuous to market your product as privacy focused then put the onus on the user to actually make it private. You can do that with any browser. If you're just going to end up shaving the yak anyways why use Brave to begin with?
What’s not private about the ads. Brave uses a pretty ingenious way of serving targeted ads.
All the tracking is local on the device. The browser is sent an ad bundle. The browser chooses what ads to display, locally.
Also viewing ads to support the product is opt in, not opt out.
Is there some ethical gray area around an ad blocker funding itself by displaying different ads. Sure. Is it automatically anti-privacy to serve ads? I’m not so sure it is.
As to your question: it depends on why they are jumping. If it is because a giant truck is going to run over us, I might join them, yes.
