The messaging feels deceptive to me because it seems to be pitched with juvenile "you should be able to have as much as you want without having to care about price!" tone, rather than the more nuanced concern that monopolistic ISPs could promote or deny traffic in anticompetitive behaviors. That concern, while real, doesn't seem to have shown much threat of manifestation outside of a few edge cases (two that immediately spring to mind are Comcast throttling torrents back in ~'07 and T-Mobile not counting bandwidth consumption against quotas for near-edge hosted media from their their "Binge On" partners). It honestly seems to me that the number of "consumer-friendly" neutrality violations have outnumbered the anti-consumer ones in recent history - which is a concern in that it makes it harder for a startup to compete with an entrenched player, but that's WAY outside of any of the messaging being pitched to the unknowing masses today (probably because "companies giving you service perks for no extra charge is bad!" is a hard message to sell). Things like the Verizon/Netflix flap was a peering dispute, which isn't a new concern and probably isn't resolved to any real degree under neutrality regulations, but people still reference that as a flagship case for neutrality regulations.
There are some legitimate fears. Most of them haven't manifested, and are most robustly resolved through opening up competition in the ISP space, IMO. The messaging seems to be, in the majority case, unrealistic scare-mongering, and that leaves a bad taste in my mouth.
