Net-neutrality has been a contentious subject in Washington and the latest turn in the saga is over the new rules put forth by the chairman of the Federal Communications Commission to permit firms to pay Internet providers to deliver their content at faster speeds.

The rules, proposed earlier this week by FCC chairman Tom Wheeler, have been met with criticism internally and from start-up and consumer groups, who have raised objections that the increased costs would eventually be passed on to consumers and would adversely affect nonprofit websites, according to The Washington Post.

Wheeler has found opposition from fellow FCC commissioners, including fellow Democrat Jessica Rosenworcel. Earlier this week, citing “a torrent of public response,” she asked for a one-month delay in voting on the proposal, The Post reports.

Wheeler, however, has issued a press release to announce he would continue to push the plan, which needs three of the five commissioners’ votes for passage.

Rosenworcel and another Democrat commissioner, Mignon Clyburn, did not say which way they would vote. However, Clyburn suggested she was not in favor of “pay-for-priority arrangements altogether.”

The FCC was scheduled to vote on the first draft of the rules on Thursday, The Post reports. Another version of the rules, one which prevented Internet providers from selling faster download speeds, was “struck down by a federal appeals court in January,” according to The Post.

Tech companies including Amazon.com, LinkedIn, Facebook, Netflix and more than 100 start-ups, have asked the FCC to drop the plan, issuing a statement in which they said it would allow “providers to discriminate both technically and financially against Internet companies and to impose new tolls on them.

The passage of the new rules is not a foregone conclusion because the two Republicans on the FCC commission do not support it.

“(Wheeler) was walking a very thin tightrope between the public-interest demand for an open Internet and Internet service providers’ willingness to only live with light-handed oversight,” Gene Kimmelman, president of the nonprofit group Public Knowledge, was quoted as saying in The Post.
