Like their data caps. A while ago I saw a progress bar on my account page. It had a caption: "For informational purposes only" and was a data usage bar out of ~300GB.
News picked this up and Comcast said: "No, we aren't doing data caps at this time".
Months later, they formally rolled out data caps of 300GB.
Even if they mean well, eventually a board member is going to wonder how to make the next $250M. Then this idea will come up. If it's not expressly forbidden, and it will boost the bottom line, eventually somebody will be compelled to do it. Fiduciary responsibility and all that.
