No. People would like to hear from the developer, but no one demands him to post in this thread. The way F95 works is that user post the developers content and status update on their own, gathered from official sites like patreon, their discord etc. Occasionally the developer are active here, but thats entirely optional.
If the dev doesn't have an update in 9 months, someone who paid him 5 bucks can say "There is no update since 9 months, the game is (potentially) abandoned, the developer didn't complete this game, he is possibly burned out" and thats valid, but someone who didn't support him and states the same information - is supposed to have an invalid post because they aren't allowed to comment on the progress???? What nonsensical logic is that? The second person points just as correctly out as the first person. Like which posts here are supposed to be invalid?
