FCC warns Amateur Radio operators to not commit crimes

It's easy to be partisan here and one is reminded to be careful to not overstep the mark.
The obvious issue is that AR could be used to circumvent or bypass social media bans etc and that forms of obfuscation could be used to do so.
In the past, it's not gone unnoticed that AR equipment and bands have been used for nefarious purposes principally by non-licensed interlopers, so the message subtext is for licensed operators to be on the lookout, etc.
As AR is a communications medium, and given its intrinsic nature in that it can bypass the normal/usual means that the State has to shut communications down - at least in the short term - the State has concerns (even if unwarranted - as it's still a potential threat).
From the very outset in the early days of radio, there were two reasons for licencing radio transmitters/operators, one was to control interference and the other was fear by governments that information could leave a country's borders without the government's knowledge or its ability to stop it, hence strict licensing.
In the early 1900s governments were truly paranoid that foreign agents etc. could use radio for war or insurrection etc. It was a very big deal. (Note the shutdown of AR during WWII for similar reasons.)
Governments everywhere still worry about this. Note the rules around mobile phones which have similar issues. The international mobile standards make it compulsory that phones send IMEI and serial numbers to cells for ID etc. to ensure that the communications can be tracked/IDed.
Thus I'm not a bit surprised that the FCC issued this warning given the current political unrest.
My understanding is that most of the planning for the Capitol assault was done on Facebook groups. Some of those who stormed the Capitol were using walkie-talkie software on their phones.
If the FCC has proof that hams were using amateur radio for the event then they should tell us.
