brave is the most shady. at least google microsoft tells you while they spy on you. brave has:

installed a vpn with a running service without telling its window users in an update. also made it reinstall every update until they got called out and users kept complainiong. i mean they did eventually..

if you use brave search without the brave browser they would turn on on the send analytics option back on no matter what you do. ofc this was in secret like after you reopened the browser etc. every other setting would save.

the most popular privacy browser comparing site is owned by a brave employee. it was almost impossible to find this disclosure but they since have made it a bit more easier to spot. still the way they do tests is pretty sus. like testing out the box when they know they have a blocker and certain important settings on

etc etc. i mean i guess its not so surprising their job is hiding thing.

i used to use brave. even when i switched off i used brave search default. but the fact i couldnt turn off analytics, or more so they fact they made it look like i could turn it off made me never lose the last amount of respect i had for those guys. i mean i dont even care about privacy anymore really, i use edge. its just the shadiness that turns me off
