The Federal Communications Commission has voted on party lines to undo sweeping Obama-era “net neutrality” rules that guaranteed equal access to internet. The agency’s Democratic commissioners dissented in the 3-2 vote Thursday. The FCC’s new rules could usher in big changes in how Americans use the internet. The agency got rid of rules that barred companies like Comcast, AT&T and Verizon from playing favorites with internet apps and sites. The broadband industry promises that the internet experience isn’t going to change.
