Evil is a strong word but imagine a future where ISPs chop and charge your for your data like cable and try to keep you looking at "their" content.
In UK I recently asked for an upgrade of bandwidth for which they don't have to change anything since lines are already there, I still had to sign a new 12 month contract despite being a long term customer. Did I had an option? Not really because only they all have similar terms. There is so few of them that customer don't really have a choice.
Vertical integration looks consumer friendly in short term only. In long term it just kills innovation and competition and screws up user.
There seems to be a lot of misconception about ISPs in general. I am an ISP owner and I wrote a small rant a few days ago: https://news.ycombinator.com/item?id=12691465
I think a fair amount of the anger at the huge ISPs is that they don't invest in many areas' infrastructure while raising rates, reducing the value of services by retroactively adding caps, and otherwise being exploitive in noncompetitive areas. AOLT&T (sorry, couldn't resist), in particular, is also well known to use threats of not expanding infrastructure as a political weapon, while Verizon is better known for pocketing billions in concessions while also not building infrastructure. But both do both.
Now they want to confuse, and of course raise, your bill further, blurring fees for connectivity with content.
They can even run on a loss for years just to make it unattractive for smaller/newer player.
Google and Apple control much more of the market via handset OS's. And we let them control media on their devices.
And after Net Neutrality, it's not even legal to discriminate against competitors traffic.
