I'd first ask them why they hold the opinion. You might be surprised by the reasoning they have for saying this. Having strong opinions isn't necessarily a bad thing.
The fact that it's out of context and the tone is so different is what made me take it as not so serious and just a playful jab at Elixir.
I think the interpretation everyone seems to be taking (which is surprising to me personally!) is such that it's like Elon requiring people to put "Parody" in their name.
It just seems completely out of context and aggressive. ¯\_(ツ)_/¯
