Personally, I assumed you either didn't want criticism at all, or just not in the bug forum. - If I had to guess, then what gave them the impression that you just outright deleted the criticism, is that some of it got deleted while other things didn't, despite not being bug reports or questions either.
The post about the about the many reworks as well as the complaint about save file not being usable again didn't get deleted for example. The latter one admittedly looked a bit like a question, but it was actually feedback.
