I'm not sure what the persecution title is supposed to mean, but as
to the content of your post, I believe there is value in the open
and honest dissenting opinion being voiced. If you don't want that
on the announcements board, and I think you are 100% within reason
to not want that, then the obvious choice, in my opinion is to not
release any posts there, and simply move all responses to gameplay.

That may not be possible or easy with the forum software, but to
release, for instance, Rob's post, which I believe misrepresents the
discussion on Discord, feels like you are agreeing with his opinion
(which you probably do) while silencing other viewpoints.
