Why? Are they significantly more hated than any big co? Like Uber and Facebook received quite a lot of bad press lately. Is this just perception or are they really that bad/evil?

TMO (yeah Austria, not US but still) were bragging about not hashing passwords on twitter just a couple of weeks ago. Not exactly professional.

In the US they are. Comcast has rather notorious Customer Retention policies and frequent abuse of their position as monopolies in many cities, whether it's a matter of the prices, the data caps, the script injections, the promises made to cities that never materialize, and so on.

It's basically like comic book villainy, the only thing missing is photos of Comcast Executives cackling over the complaints from customers. And I say that as someone who was overall okay with Comcast's service the one time I had them. The behavior of Comcast defines the perception most of the US has with them.

Well good companies are one which write same CRUD apps Nth time. And then in few months/years they either shutdown or join forces with a bad company.
