Consumer unfriendliness can be at multiple levels, not just in a falsely advertised plan. The FTC sued AT&T over wrongful advertising and changes of a data plan, a consumer affair issue.

Figuring out whether your ISP is correctly being the common carrier it needs to be (correct or incorrect prioritization, 0-rating, caps, etc..) is definitely a Title 2-related communications & FCC issue. The FTC can continue enforcing what are consumer affairs issues related to ISPs being broadband providers. The FTC's legal reasoning is correct, getting rid of the exemption as I understand it would give them more authority if their current argument is rejected in court.
