I think Wipr is also very trustworthy. It’s developed by an indie dev who’s responsive over email, and gives you a lot for free. And it has a $5/yr subscription (or one time payment) that unlocks system-wide ad blocking, not just in web views.
I’ve found it to work exceptionally well after trying other free adblockers.
Yeah my comment wasn't me trying to say they weren't trustworthy, I've actually purchased both AdGuard and Wipr but I stick with AdGuard since I felt like it was better. And the dev of Wipr seems to be transparent for sure.
However of the three I trust AdGuard the least, for no objective reasons.
