The gates are open on what may be Facebook’s last sitewide vote, according to a post at its site governance page. Facebook proposed a round of changes to its data use policy and statement of rights and responsibilities, one of which will remove the site’s self-imposed need to alert users and solicit their feedback on changes if they are of the legal or administrative kind.

In addition to removing the feedback solicitation and votes, Facebook is also giving itself permission to share data with its affiliate companies. This also allows it to communicate data between the US and European contingents of Facebook. This clause will free Facebook from having to keep its Instagram data separate, which Facebook has been doing since it acquired the startup earlier this year.

The changes in the data use policy include a reminder that hiding a post on a timeline is not the same as deleting it; the hidden element may still appear in the news feeds of the intended audience. Another subtle language change now prevents users from using their personal Facebook profiles for their own “commercial gain”; instead, they must use a Facebook Page for such purposes.

Facebook first announced that it would implement a democratic process to policy changes in 2009 and that a 30 percent voter turnout would make the results of those votes binding. Two votes have since been held, the first with over 600,000 votes cast and the second with 342,000, the latter out of a scant 900 million users. Based on that history, it’s safe to guess that the required 300 million Facebook users won’t rally and vote against the removal of their vote.

Facebook has posted versions of its Statement of Rights and Responsibilities as well as the Data Use Policy with tracked changes. The voting page will remain open until December 10 at 12pm PST.
