Relatives of three victims of the Pulse nightclub mass shooting in Orlando have sued Facebook, Google and Twitter for giving "material support" to ISIS, USA Today reports.
The lawsuit, filed in Michigan by the families of Tevin Crosby, Javier Jorge-Reyes and Juan Ramon Guerrero, claims those tech companies have made it too easy for ISIS to spread its message.
"The explosive growth of ISIS over the past few years... would not have been possible [without those companies]," the lawsuit reads.
The lawsuit faces an uphill battle -- federal law protects publishers from liability for others' speech. In other words, it may be hard to prove Twitter is responsible for allowing ISIS members to use Twitter.
But the lawsuit claims the tech companies are liable because of profit-sharing and advertising. The plaintiffs allege the companies combine ISIS posts with ads that target specific viewers, which may count as creating original content.
Background on the shooting
The owner of the nightclub, Barbara Poma, briefly entertained the idea of selling the club to the city to create a memorial, but opted not to, saying she intends to "create a space for everyone, a sanctuary of hope."
