Being able to side-load a random unsigned binary via the fdroid app, or getting it from the F-Droid repository where they do independently signed (and ideally reproducible) builds, are very different things.
The F-droid team does not have a high bar to be dicks. They do it to ensure their users get binaries that match the published code to prevent increasingly supply chain attacks.
The standards are there for good reason, and if you do not understand those reasons, then use a license that allows the people that do understand to distribute your software for you.
Very very few software engineers understand supply chain attacks or how to prevent them.
