With that said, I would agree that some other services such as information seekers ought to be regulated somehow. Ie, Google/Facebook can do massive harm these days, and their reign of independence is failing here.
Another point is that, many companies have previously ran into issues of anti-competitive behavior. This in recent years has become very very lax, too lax I feel. Windows should be providing an equal platform for everyone to run on. They shouldn't be blocking competitors applications (a hypothetical). Same goes for ISPs. My ISP shouldn't block Netflix because the ISP prefers their own media site.
To be honest, your objection really confuses me. You seem to argue that ISPs can do whatever they want, because we're inconsistent with other sites/etc. So rather than enforcing other sites, you want to give free reign to ISPs? How does that make sense? I agree consistency is important. Lets fix all abusers, not just ISPs. That should satisfy your argument, no?
