A social media alternative to Twitter, called GAB, is suing Google saying the Internet giant falsely labeled it a hate speech forum. Google has banned Gab from its popular store that sells applications.

Earlier this year, in our cover story the "Sum of Knowledge," we introduced you to Gab founder Andrew Torba. The former Silicon Valley worker, says the industry colleagues discriminated against him when they learned he was a Trump supporter. He started Gab promising not to limit legal speech, saying conservative voices are routinely suppressed on social media. Torba told us Gab has been smeared as alt-right and white supremacist, even though his co-founder is a Turkish Muslim who opposed Trump. The lawsuit claims Google has an unfair, monopolistic advantage over startups like his and is violating antitrust law.

The head of Google's parent company, Alphabet, worked on the Hillary Clinton campaign. Alphabet was Clinton's second largest donor. Gab has about 268,000 users.
