The thing is, this forum is answered by the community, not the staff (no, the moderator is a volunteer, not an Itch staff member).
I understand your frustration, but what the moderator is pointing out is that you're not contacting the staff here, and they're not going to respond. So, there's really not much point in continuing to insist this way. Personally, I don't see a problem with you doing it, but you should keep in mind that the staff isn't going to respond or provide a solution through this channel.
Regarding the problem, from what I've seen (and personally), this issue doesn't affect all users. I haven't had any problems accessing the application, and perhaps that's why the staff hasn't been able to resolve the problem, since they may not have been able to reproduce it. And to answer your next question, no, Itch doesn't have an IT team dedicated to patching the application (please don't ask me why, I don't know; I don't work for Itch either, and I'm simply explaining how Itch works, not defending it).
The application is open source and on GitHub. In theory, anyone who knows how to solve the problem could commit the solution.
