Many of the companies that are "pro net neutrality" or at least are incentivized to support it have many, many, many other concerns for lobbying, legislation, and budget. Engaging in a race to the bottom over a single issue is probably not a strategy that people are willing to take.

ISPs on the other hand have few other issues quite as important.
