This was a bit unexpected for me as well.
Here you can see the change that was made on F-droid: blokada: 22.3.8 (f325ad20) · Commits · F-Droid / Data · GitLab
It appears nothing malicious was embedded in this release, however it triggered a new kind of bug at start up since it hasn’t been tested by Blokada at all.
So it appears that any random guy can submit changes without any kind of approval (including editing the source code and behavior) to any app hosted on F-droid. While it probably was with good intentions to make the latest version available and was hopefully reviewed somewhat by F-droid maintainers, it is also scary that this is even possible. You can’t really trust that “the source” that an app links to is truly what you’re installing.
What’s even more interesting is that previous attempts by Blokada to satisfy new requirements was denied. But a random guy can get a pass.
This behavior doesn’t exactly add anything to my confidence in supporting F-droid as a platform for Blokada in the future. I believe most users expect apps to be signed by the author of the app and not modified at will by the app store you download it from.
