Writing from Brazil here : still over 70% of the visitors, on average, to most sites I monitor are using some version of IE.
So claiming a "feature" like that down here would be like rejecting 70% customers on a popular mall because they're not wearing red shoes(or some other arbitrary reason).
Except it's not arbitrary. Each browser they support adds development costs and takes time from their devs.
It is more like choosing not to serve vegan options at a dinner. Sure, it might piss people off but they could always suck it up and just eat the bacon.
