WASHINGTON - The Federal Communications Commission's vote last week to repeal its net neutrality rules marked the end of a brief experiment by the network regulator to rein in the tremendous power of internet providers by treating them like the highly regulated telecoms. Now, providers will be allowed to speed up some websites - and block or slow down others - so long as they disclose it to the public, and violations will largely be handled after the fact by the Federal Trade Commission, not the FCC.
