You don't even need add blocking for most open source software: the threat of forking backs a culture where the software is just there to to its job and not to sell something.
I started using the f-droid app "store" recently and it's amazing: bare bones stuff that just does what you want.

- Limited offer modals - "Hey we have a useless AI chatbot" popups - Cookie banners - Newsletter popups - 3 tiered subscription offers for everything - Sign in to XYZ with google - This site wants to know your position
And don't even get me started on things you can't change as a user like really bad full text searches and stuff.
And I'm still yet to find that hot single in my area.
