The only reason Mozilla still exists is because Google needs them to so Chrome can't be a complete monopoly.
Their priorities have always been... questionnable. Like, we got FirefoxOS all while Firefox was basically unusable on Android and Chrome rapidly eating their lunch, PWA support was abandonned then removed, which was the whole idea behind FirefoxOS... Then they started Servo, the rewrite of the rendering in Rust only to cancel it midway.
But hey they acquired an ad company, as if people don't use Firefox so uBlock keeps working. And Pocket, and VPNs and a whole bunch of other crapware nobody wants from Mozilla. It's like they go out of their way to be the second option.
