It's not like there are many lawyers left who are willing to represent them. Either because they have behaved so utterly vile like Alex Jones, the case is so clear cut due to their own behavior that there is zero chance of achieving more than a token reduction in sentence (while risking the ire of the clueless fanbase for a "bad defense job") like in this case, or because they have a history of not paying their bills like Trump.
That leaves only those as lawyers who already have zero reputation left to lose, want to make a name for themselves in the far-right scene, who are members of the cult as well, and those who think they can milk an already dead/insolvent horse.
These are often also simply hard clients.
Jones is a good example of this. He cycled through about 20 different lawyers during the sandyhook trials. The reason he was defaulted is because when he was required to produce something, he fire the lawyers (or they'd quit), hire new ones, and invariably in the depositions an answer to "did you bring this document the court mandated that you produce" the answer was "oh, sorry, I'm brand new to this case and didn't know anything about that".
Jones wasn't cooperating with his lawyers.
There are plenty of good lawyers that have no problem representing far right figures. The issue really comes down to those figures being willing to follow their lawyer's advice.
The really bad lawyers simply don't care if their clients ignore their advice.
Don't forget lawyers who are worried their clients will ask them to do something illegal and don't want to be involved with that, even to reject it.
