I feel for him being in his tough spot, but let's be clear on what faker.js is. I suspect many companies (like mine) use it to create "decent"-looking data for tests. But we could trivially do without it, and basically just used it because it was there. I contrast this with some other open source projects we use that we specifically contribute to (using GitHub donations) because they are central libraries to our code…
How often have you implemented a trivial feature and, after adding tests, debugging, doing code review, etc, you find it’s taken a nontrivial amount of time. And it’ll likely take maintenance too as you learn what you need (easier when you’ve seen it done already). Most of these trivial things probably take nontrivial time, and if you add all of them together for all the trivial projects you use, it’s probably saved…
It's really a content library, which is useful, but it's not in the mission-critical category where developers can get a rubber stamp budget approval from their boss. It's a great project to get your name out there as an open source developer, rather than a viable business model IMO.
