Video-sharing platform and cloud services provider Rumble has filed a defamation lawsuit against the co-founders of Check My Ads, a watchdog organization.

Rumble’s legal action follows a similar suit by X Corp against Media Matters, signaling a broader effort against entities attempting to stifle dissent and manipulate public opinion online.

Rumble, known as a free speech alternative to YouTube, claims that Nandini Jammi, Claire Atkin and Media Matters for America, who have targeted news outlets not aligning with their political views, aim to silence competing points of view.
