Is something going on with the repo?

I noticed that many people use unofficial F-Droid clients and wanted to say that unofficial F-Droid clients harm the official F-Droid mirrors because they don’t handle them correctly. So please 🙏, if you don’t heavily relay on some feature in unofficial client, try the official: F-Droid Basic kr Classic. F-Droid Basic is the most secure too.
What is the source of this info? If it was doing serious damage to them they wouldn’t publish these clients on their platform.
