UMatrix: "is no longer available because it doesn't follow best practices"

A trillion dollar company is screwing me again. Any tips on how I can keep supporting them?

When a company shows you who they are, believe them. If an ad company selling you a browser says you don't have permission to block ads, what makes you think they won't be making (or have already made) other customer hostile decisions?

There's alternative browsers out there, some of them quite good.

If you absolutely cannot stop using a Chromium-based browser, uBlock Origin Lite might be good enough for you: https://github.com/uBlockOrigin/uBOL-home

I started using uBlock Origin a while ago instead of umatrix and it did what I wanted automatically. Brave has it integrated so its not going away, despite Google's wishes.

I'm using AdGuard DNS on both macOS and Android.
