Is this a violation of the 1st Amendment or a way to skirt around it?

Perhaps you should actually read Taibbi's work in this thread.
Imagine how this my play out in a future election with different candidates.
In principle, certainly it is not great for security services to meddle in public spaces. In reality, I am willing to believe that the federal government is a tiny fish in the sea of requests from local authorities, individual police departments, private individuals via reports, not least of all the legally persons we call corporations. I bet any day, Twitter's moderation teams are blanketed with requests from companies and businesses of every type and size, both advertisers and not. All equipped with legal teams that could potentially target Twitter.
In short, I find it to be performative virtue-signaling to be concerned about around a dozen small potatoes that the FBI asked for the mods to take a look at. Especially if this might just be cover for the real large-scale systemic censorships that occur at some deeper level that no FOIA or Taibbi journalism would be able to unearth. Especially when the PRISM programs are right there if you want something of substance to be outraged about. This, in comparison, is no different from a mom and pop store asking Twitter to go after an abusive account spreading slander about them. Litigiousness is an all-American custom. This didn't even trigger any warrant canaries. Hysteria over this is concern-trolling.
