If your internet isn't very good now a days odds are your not buying games either, or paying for memberships. So there isn't a point to catering to them because they don't have as much spare money to spend on video games.
From what I've seen the quality of internet connections depends completely on where you live, not how much disposable income you have. Especially true in areas where there's only one ISP available (way more common than it should in the US from what I've heard), those tend to have it the worst since there isn't any competition so the ISP can get away with pretty much anything.
