It's like that with every competitive game.
You see other people playing it and think "wow, that's cool. I wanna try it", only to be welcomed by what you just described. Your success then depends on whether you have a hard skin to endure the bullshit, or if you're social enough to have others play with you that won't dismiss everything you do so easily. More often than not we don't have the patience/ability for either.
I wouldn't mind doing it. I run my own DNS so it wouldn't affect me, but I figure if they're already trying 8.8.8.8 they may as well try 8.8.4.4 and perhaps more, so it'd require a bunch of firewall rules.
Now, all of that is moot point cause I hate the whole "smart TV" thing, so they'd never be connected to the internet.
