It is of course ridiculous to suggest that people voted for Trump hoping he would destroy a free and open Internet; we have clear and incontrovertible evidence that the vast, vast majority of citizens (90%? 80%? I think it depends on which poll you take) hates what he is doing. The president has a good-faith responsibility to represent the citizens and when they come down on an issue like this which was non existent or tangential to his campaign so fervently it's most certainly a betrayal of that consent.
When he tries to build a wall? Sure, he definitely has consent there. On NN? Not a chance. He does have power though.
