The problem is, this is not an American street corner - this is I-hub and there is a TOS agreement.
Freedom of speech dosen't allow you to stand in a crowded theatre and yell fire! And it doesn't allow you to take up board time with a rant on any topic you choose.
Without the ability to remove posts that violate the TOS I-hub would be another RB, and we know how that worked out.
On the other hand you CAN start your own board called the "I hate PYPR board" and scream all you want. Still can't violate TOS agreement tho.
