i wonder how linux does it?
linus and anthony should have a head to head.
I think you are comparing apples to oranges here. Linux is made of many distros, each one with their own strong points and features. Many different maintainers matain them. There is no single point of funding for them.
Mozilla on the other hand makes basically one semi well-known product (and other even less known stuff) and gives it away for free.
If tomorrow Google pulls the plug, who will pay for the salaries of the engineers who maintain Firefox? The general public does not care if Firefox lives or dies. In my circle of friends and family, I am the only one who uses Firefox. Most people are on Chrome or Brave. That's it.
Someone in the comments above mentioned that Mozilla could release a paid version for Enterprise customers, imitating Red Hat in a way, but I am highly skeptical that Enterprise customers in times such as these will be willing to pay for something that they can get for free from Google or Microsoft.
I guess we will have to wait and see.

they don't? There's no company, or rather - a lot of them, Linux kernel moves forward like 80% by corporate contributors. For some of them it's critical part of their infrastructure, some of them need to get their device drivers mainlined, for some of them it's gpl magic at work. Linux desktop experience, however, leaves a lot to be desired.
Companies aren't interested to contribute to a browser when they can just reskin chromium or build on blink directly and community cannot match the pace.
