No, that kind of group think is a consequence of not having proper freedom of press and proper freedom of association in the country. Which in turn is a consequence of voting for Erdogan (even if not everything was roses on that front before Erdogan, to be fair).
As for businesses being threatened, how many media businesses have been closed by Erdogan? Free press is not optional for something that claims itself to be a democracy. Turkey is worst in class in that department, and as long as that is the case, whatever people support doesn't really matter, because the leader can dictate what news they see (or not).
>"As for businesses being threatened, how many media businesses have been closed by Erdogan?"
Erdogan and Gulen organisation in police and in judicial system done those things together. Every trial that is against Gulen's opponents contamined with fabricated proofs.
>"Turkey is worst in class in that department"
I sadly agree with you.
>"whatever people support doesn't really matter, because the leader can dictate what news they see (or not)."
Things are a bit complicated than that in Turkey. Most of the people hated Gulen's organisation before 2013, where Erdogan and Gulen media protected and praised him. Also other political parties support Erdogan in this case...

The teachers and other of the movement that wasn't involved in any wrongdoing are still part of those getting hit by the witch hunt.
