This malicious behaviour is not okay out of anyone - leader or follower. When I was a kid, my parents asked me to consider the position: If my friend told me to stick my finger in the fire, would I? For those that shrug and blame it on Linus, I ask you also to consider that position; you're not 4, you're capable of critical thought. Stop being a dick and blaming it on others. You being a dick is on you, period.
I don't care if this is the example set by Linus himself - just because he does that, does not grant you leave to behave that way too. If he acts that way, I will consider him a dick. If you do that, I consider you a dick. I don't look at you, shrug my shoulders and say "Hey, I don't blame you, I blame Linus for setting a bad example." I judge him for his behaviour and for acting that way while being in a position of influence. I judge you for bad behaviour as well as bad judgment for considering that you can blame someone else for your own bad behaviour.
If you're working in a community that has garnered a reputation for poor behaviour because of its leaders and/or constituents, don't become that, you're better than that. If your leaders are like that, don't be scared to call them out. Bad behaviour is bad behaviour, I don't care who it's from. Respect garners respect. If you're a dick to people, you don't deserve respect. It's okay to hold people accountable, it's okay to hold them to high standards, but stop being a dick. That's not okay.
