I haven't done raids/ex trials for years but i have seen from time to time PF advertisements with:

"No PS4 users"
"Must join discord and show us your FFLogs"
"Elitist PC masterrace raiders only" --- This one i seriously saw this week lol.

At the end of the day it all comes down to the number 1 reason: 3rd party Apps lol. That is the only reason i could think off why a elitist PC raider would call someone a PS4 Console Peasant.
