Mozilla doesn’t exist to fund Firefox. Firefox exists to fund Mozilla. It’s been that since the very fucking beginning: Mozilla is a general internet charity that makes money with a browser. It’s always been that way. It never has been any different. I may have to repeat myself: The purpose of Mozilla isn’t to fund Firefox the purpose of Firefox is to be a money-maker for Mozilla’s charitable causes.
Servo isn’t dead it’s just on slow burn. Also, under the umbrella of the Linux Foundation Europe. As far as Mozilla is concerned it has served its purpose: Prototype stuff that then got included in Firefox to get rid of a quite large amount of technical debt.
The long and short of it is: Firefox is supposed to make money for Mozilla’s charitable causes. It’s not an end in itself, but a means to an end.
