I don't use Brave, won't use Brave, and have my reasons for it.
Brave is Chromium based; a project which is slave to the whim of Google.
Brave integrates an unnecessary cryptocurrency.
I hate shitcoins
Brave does not block ads! It does not 'enhance' your privacy. It just absorbs some ads, replaces some, and blatantly lets first-party advertisements through the filter. That's not ad-blocking
Brave does not protect your privacy. As per my previous point; it does not block ads, it injects it's own right into browser chrome! That's worse than plain Chrome! Your privacy is automatically violated when you watch/view even a single ad.
Brave does not have many benefits above "Ungoogled Chromium" or other competing projects. It just doesn't. Unless you like marketing fluff.
Brave is NOT BETTER THAN Firefox. It's worse; because it's Chromium; which is enslaved to Google whims. Don't believe me? Try to contribute something to Chromium that goes contrary to Google's stated goals and watch how fast you get shot down.
