I have no problem with cursing per se, but going after Charlie is disrespectful and shows Vettel can't get a handle on his emotions. Did you read his apology after the fact? It was sooo over the top. He drove into Hamilton on purpose which shows he can't handle his emotions.Exactly how is it telling anything? Her cursed at Charlie, so what? Lots of drivers curse on the radio and don't forget that cursing doesn't always sound as bad to non native English speakers as it does to native speakers. For example shit (the English word) is used in Dutch quite often without carrying a heavy load unlike in the US. Not saying cursing at Charlie or cursing in general is OK but they are busy driving, adrenaline is flowing and I can understand polite language is probably not the first thing on their minds when they feel they are getting penalized unfairly.
Same for multi 21. So he wanted to win and did so by being an ass. You don't become WDC by being nice. Perez didn't let his teammate through last race despite the team asking and in Baku they crashed into each other. Verstappen didn't let Sainz pass either despite the team asking etc. Schumacher dove clean into his opponents on two occasions in an attempt to win and if Rosberg ever opens up about it I'm sure Hamilton hasn't always been exactly nice/fair either.
Grosjean and Maldonado are totally different as those two just crashed into anyone and everything by themselves.
