Likely a combination of the reasons you listed but given that past protests against ending net neutrality were quite extensive, I'd say protest fatigue is a large part of it. And not just fatigue over the ending of NN rules seeming to be inevitable due to attacks on it seeming to never end but also protest fatigue in general. Protesting just about anything in order to gain social currency has burnt people out, and now we're all left vulnerable due to protest energy having been spent on issues such as 'air conditioning is sexist'. People are tired of being asked to be outraged all the time, which makes it an excellent time for pushing through what would otherwise be unpopular changes.
