Comment A) "Screw Mozilla, all their funding comes from their Google Search deal, they're just Google in a mask"
Comment B) "Screw Mozilla, they waste all this money on side projects (that would provide non-Google revenue streams) when they should be spending all of their effort on Firefox (which is effectively un-monetizable apart from the search deal - and you can bet hard money there'd be screaming if they tried)"
Can we at least acknowledge that most of the side projects did lead to improvements in the browser and web ecosystem? FirefoxOS led to a bunch of focus on memory usage & responsiveness as well as web APIs that provided more parity between web and native apps. LetsEncrypt got a big boost from Mozilla as did Opus and AV1. Rust is in a class of its own. The VPN deal doesn't require that much investment from Mozilla since it's based on Mullvad. The voice & language database is a big boon to the current open source AI training movement, etc.
