looks like rendering adblockers extensions obsolete with manifest-v3 was not enough so now they try to implement DRM into the browser giving the ability to any website to refuse traffic to you if you don't run a complaint browser ( cough...firefox )
here is an article in hacker news since i'm sure they can explain this to you better than i.
and also some github docs
You can support by joining the project and helping them to fix issues. It's a young project, but they've been progressing really fast. Andreas Kling is one of the original developers of Safari, and in the past years he's been creating his own operating system (Serenity OS) and formed a team who've been doing their own JavaScript engine, web browser and a programming language together with the OS. It's a really fascinating story and I give all the respect for them for doing this. This is the work we have to do if we want to beat Google from taking the internet. It's us who need to step up and start fixing the internet.

I don’t disagree with you on alternatives but again it’s challenging for the technical folks amongst our peer groups to help adoption of an alternative if we can’t provide places for the folks we support to download the alternative and try it
There’s no way for any of my family or friends to understand how to build their own browser, let alone setup a WSL2 environment to make it work. Their eyes are going to glaze over at the thought then they’re going to go download something else.
That time is not yet. Give it a few years and if you're willing, join the project to help. There is movement, it's just about how can we help.
