Money isn’t important. Some complex software is, in fact, maintained by unpaid volunteers who feel strongly about the project. That doesn’t mean it’s easy (in fact it’s quite difficult to keep the lights on and the code up-to-date), but it is A Thing That Happens despite being difficult.
What is important is the size of the codebase (in the case of a fork, that’s the code either written for the fork or code that the fork preserves and maintains that isn’t in the original anymore), the length of time it’s been actively worked on, and the bus factor. Some would-be browser forks are indeed trivial and ephemeral one-man shows. Others have years of active commit history, carry tens or even hundreds of thousands of lines of novel or preserved code, and have many people working on them.
