1) Completely false for uBlock Origin; zero relationship 2) It's fully open-source so the above is verifiable 3) AdGuard and every single other (proprietary) adblocker for Mac and iOS includes content blockers, but also includes web extensions that request access to "all web page contents", including credit card numbers you type in, allegedly for the purposes of custom element blocking etc. (not open source, we can't check). Try installing it and see. Apple still allows web extensions that have complete access to all webpage contents (which is necessary for many legit extensions), they just block specific WebExtensions APIs that uBlock Origin requires. Literally zero benefit to privacy whatsoever, yet everyone buys the BS.
