So you know, abusive companies should be punished. But lets be honest here, politicians are targeting the likes of Microsoft, Google or Apple not for our own good, but because they see a huge pie that isn't theirs and want a piece of it, with people forgetting that these companies have defined the huge markets they are dominating in.
And I'm saying this as a European citizen that had plenty of diatribes against all 3 companies mentioned here - but I do not believe in government interventions when it comes to software and yes, I don't believe in net neutrality either.
For many people in the US, they're completely stuck with Comcast or Verizon and likely will be for decades to come (Google Fiber's complete roll out will obviously take a very long time). They either have to move, or suck it up.
Microsoft was forced to include a browser choice screen and not use IE by default on Windows computers sold in the EU. The same happens here - you have different responsibilities when you're in a dominant position.
