People mixing up terms in the action economy. Basically "bonus action" as a term causing all sorts of problems, either players thinking they can just make a second action as a bonus action, not knowing what sorts of things they have that actually qualify as bonus actions, or thinking simple free object interactions or shouting a word or phrase while running count as bonus actions. More of a pedantic pet peeve about the RAW not really doing a very good job with nomenclature or specifying which sorts of things are which.
I blame this more on DMs who "do things different" for no particular reason other than they Feel Like It*TM. I think a lot of people get confused for the simple matter that Some People like to declare the game wrong and position their opinion as fact. I've played at more than one table where simple interactions, short statements and so on count as bonus actions, or even full actions! For no more reason this time over the last time than DM whimsy.
