That's interesting, I do think that there are a lot of people who unnecessarily complicate their communication for reasons of insecurity, not just because they could be making claims that are shaking or easily exposure as fraud or falsehood.
I see it a lot in people who've not had much or any higher education (or just spent their higher education doing sports, partying or lounging) who then read complex texts and try to adopt the styles or language they find there, the results are lousy, great you've read adam smith, the constitution, what not, dont assume you could or should write like them.
There's a lot of it and some of it also shows pretty conflicted attitudes too anti-intellectualism combined with the attempt to perform as an intellectual in that arena, the whole playing dumb thing that got mentioned a while ago, as a "debate tactic", I dont even get the whole "debate" idea even, discussing politics isnt like playing Call of Duty or Fortnite and a hell of a lot of people behave as though it is.
In the grand scheme of things this "debate" idea is about stopping people examining their own views or others.
