Zen (Full-OS Ad-blocker)

Looks pretty cool, not sure of it’s compatibility with VPNs or Tor though.

Any reason to use this over an ad blocking dns? Plus, what purpose does it serve, usually one only sees ads in their browser…

No!

This installs a root certificate to directly manipulate traffic.
You must trust that it absolutely handles all TLS interactions properly, and even then it’ll obscure your browser from handling that correctly.

You’re far better off using basic global DNS-based filtering combined with a powerful in-browser content blocker (uBO).

Marking as rejected, SSL MITM is an unacceptable security risk as described above regardless of the client and whether it’s open source.
