Intel, Yahoo, Amazon, Pandora and Spotify are the latest big-name tech companies to sign on to a legal brief supporting transgender rights, a source told Axios.

The firms join Apple, Salesforce, eBay, IBM, Microsoft and others, who will file arguments in the case of Gavin Grimm, a Virginia high school student who is fighting for the right to use the restroom and other facilities that line up with his gender identity.

The Trump administration has withdrawn Obama-era guidance that sided with Grimm, but ultimately it will be the Supreme Court that gets to decide whether existing sex discrimination law protects protects the rights of transgender people.

Who's still not on board: Google and Facebook have yet to sign on, sources said.
