It's really standard to leave some time for users to adapt when making a big change. Especially end users. It's actually a good thing, the "friend showing up" analogy makes no sense.
End of support for users is June 2024.
But it did seem to have changed a year ago or so, my bad.
For system wide DNS blocking you only have two options: use a DNS server with blocking (either your own with something like a piHole our a public one) or use the hosts file.
But it's also true that sometimes it's not done with a pro-piracy stance but they would just rather have it pirated than bought through key-resellers as these can hurt indy-game dev a lot.
You are conflating the two meanings of free. Pirated software does not improve your freedom and open source is not necessarily free.
That being said I've seen a few indie game studios making pro-piracy statements or even putting the game on torrent networks themselves. But these are the one that deserve the most to be paid.
No filter list that can be updated, you have to update the whole extension to update filters. This adds delay as it has to go through Google verification process, they could even refuse some updates.
Not every type of rules are available on MV3, so it has to drop some filters.
While the code being open is good you still have to rely on trust.
I certainly don't have the time to review to code of each extension I use. And even then, we have no garanties that the extension distributed through the browser stores has the same code.
You can see the issue was opened on august 18th but the responsible commit was only made on the 19th. So the code was pushed the extension users before it was made available on the repository. Open code is of no help here.
I agree, there are a bunch of annoying limitations. But it's better than nothing. To me the best vim based browser is qutebrowser, too bad it's using chromium.
Cookie autodelete doesn't work with strict mode and you should use strict mode. Just drop it.
You don't need an extension to auto remove cookies with Firefox.
