Again, what exactly are you talking about?

The lead developer recently started a thread in the Piefed meta community specifically to open for people to ask questions about these things. In full:

I have received word that there are people combing through the PieFed code looking for anything that might be harmful. This is excellent and can only make PieFed better and less harmful.   We appreciate their interest in PieFed and look forward to answering any questions and showing people around the code. Please join us at https://chat.piefed.social or https://matrix.to/#/#piefed-developers:matrix.org.

There’s no need to listen to rumors and amateur speculation when we’re right here and happy to help. Come on in, the water’s fine!

Nobody managed to come up with an even remotely critical question there.

If you have an issue, ask in !piefed_meta@piefed.social. If the community agrees your concern is valid I can guarantee you it’ll be addressed.
