When Senna did this to Prost he was a hero. When James Hunt punched another driver, ditto. IMHO, Marquez should be penalised for his appalling behaviour on track. In a post race interview Rossi said "I took him wide and slowed right down to say What the f**k are you playing at?" Marquez leant into Rossi and brought about his own downfall. Reminds me of Schumacker stuffing it in to clean drivers like Villeneuve and Damon Hill. Unfortunately when the likes of Rossi and Hamilton retire I can see racing becoming a sanitised / homogenised, protest / counterprotest fest where just the guy with the fastest bike / car wins.
