There's also an incentive - competition - to provide services that people actually want over their own offerings. For example, here in Portugal, mobile provider(s?) are offering unlimited mobile data for services that compete with SMS, like WhatsApp, Viber, Facebook Messenger, Skype, etc.

Personally, I'm not ideologically opposed to net neutrality legislation, but I'd rather identify why is competition not preventing ISPs from violating it, and what can be done to strengthen it. I'm getting somewhat tired of laws that are just trying to fix the problems created by other laws, like those which grant privileges to certain economic groups (not that I'm saying this is the case).
