The ISP industry (three giant telecoms) spent over $100 million lobbying for it. (See how much your congressman got from the business to see if he/she will ever fight for Net Neutrality's return). Oh, and by the way, the new rules contain a provision saying that states do not have a right to create their own Net Neutrality rules.
In the most recent poll 83% of Americans were against this, including 75% of Republicans.
Drain the swamp, my ass.
