Nobody says it anymore

I've heard it explained that "hey" used to be more of an urgent way to get someone's attention, rather than a casual "hello" like it is now, so it sounded rude to some older folks.
Does it really create a stumbling block though? In a lot of the threads I see it being pointed out in, everyone does understand the OP. The people pointing out the grammar seem to be more derailing to the conversation than anything.
Plus I can't say I agree with whatever you mean by "getting their work more widely read or published". A lot of famous books that you're expected to read in school are already past modern English.
Isn't this conflating professional publishing with...general speaking though?
You have to understand as a publisher that there's different standards between doing your job and talking to people everyday.
