If you don't agree that Twitter should do something that it currently isn't, you by definition don't see it as having a problem in that behavioral domain.

Private actors controlling the use of their private resources to select which ideas they will and will not promote with them is called “free speech”. So, you seem to think Twitter’s problem is that they exercise free speech.
