Major tech companies and nonprofit groups have signed on to a “day of action” next month to protest the FCC’s planned rollback of net neutrality rules.

Organized by nonprofit group Fight for the Future, the protest will include Amazon, Etsy, Reddit, Mozilla, the ACLU, and several others, who have all agreed to show their support for net neutrality on July 12th. In 2014, a similar list of companies agreed to post banners on their websites showing support for regulation.

So far, though, there are few details on what the protest will entail this year. “Websites, Internet users, and online communities will come together to sound the alarm about the FCC’s attack on net neutrality,” the protest website says. “We'll provide tools for everyone to make it super easy for your followers / visitors to take action.”

The protest day is set five days before the first deadline for comments on the FCC’s proposal, a move that also mimics the 2014 protest. Ultimately, the Democrat-led FCC decided in 2015 to use strong Title II regulations to enforce net neutrality. The current FCC, led by Trump-appointed chairman Ajit Pai, is now attempting to do away with those rules.
