I'd call some of this stuff ungentlemanly conduct but this should've been picked up by ref officials with a probable rebuke but no card. They didn't act on it plus it is not a retrospective offence.
I must add that a lotta this stuff has been "over blown" mainly because of Rangers being involved and their propaganda machine working in over drive. Some of it reminds me of their post match reaction after Hibs Scottish Cup final win against them in 2016 when some of their bad-losing official comments were ludicrous but actually deflected away from their own abject failure after all their previous "drum-beating" re their expected positive change in fortunes.
