On the other hand...
9 out of 10 really skilled devs/engineers or profs that I met had tendency to be kinda snarky, especially when somebody's trying to do bullshit
Is lack of subtle/direct snarkiness a good thing?
It's like putting constrains on language/tools to express yourself, maybe too harshly?
Maybe it's considered normal in "cultures" where people are more straightfoward
As a senior engineer / team lead, I really have no patience for bad behavior.
Directness is the opposite of snark. If you think something is a bad idea, propose an alternative. Or work with the person. Anyone can throw out snark, it takes a "really skilled" person to do something productive instead.
It's quite possible to call out and dismantle bad ideas, without making it reflect poorly on the originator of the idea.
A snarky tone can have an underlying implication that the idea was so bad, the idea originator is not even worthy of a respectful reply.
Maybe this is warranted in some cases (e.g. a bullshitter bullshitting), but in the case of coworkers/contributors with good intent, this is just unnecessary abrasiveness.
