It is a major issue. People need to be able to play and tinker. As a child/teenager I didn't have money to pay for servers online but I still wanted to mess with that stuff.
My ISP didn't enforce the no-servers rule so I was able to run home servers but you shouldn't have rules that violate net neutrality that you "choose" when to enforce. People need to be able to tinker and figure things out without artificial restrictions that exist purely so that they can claim to not have bandwidth caps. It's borderline false advertisement and a violation of net neutrality.
