That's because all Tapas' actual inksgiving support is on the server, and their pre-hiding the link promotion of the forum was that the forums were a place to promote, not a community, so that's how lots of the new members see the forum, meaning all new people see is promotions, meaning they think it's the norm to just promote. And the bigger names who are really trying to make a living have no real choice but to go to the discord server to get the support from Tapas.
This is the thing really. And like, the folder forum members skew older. We're not kids who're blowing things out of proportion, a lot of us voicing out concerns are adults. Actually adults, not freshly 18 years olds. If they simply said they were focusing on the discord because all the mods are there, fine. If they say they're phasing out the forums, sure they're losing the thing they had over similar sites, but at least it's honest. If they're keeping the forums, but aren't going to support them anymore, say that. I'd rather they give us bad news up front than keep telling us we're panicking and being silly and paranoid about it only to give us no reason to trust them.
It's like "no discord isn't out favourite child we love both of you" and then going "here, discord have the forum's promotions. huh? you want something forum? no, you don't get anything".
