It’s not exploitive if you like working on it. I can see an additional upside here (for tinygrad) that they better screen out people who are just trying to optimize for job prospects or money, who would do better elsewhere, and get people who actually like contributing.
Few people with no innate interest in the project are likely to ramp up and start contributing just for a shot at a job. Whereas if you’re Facebook or whoever you are much more likely to get people who don’t care about the product and just have decided they can make a lot of money by jumping through the right hoops.
This idea that you're supposed to accept worse pay because you believe in the idea doesn't apply to George. If his companies succeed, he'll be rich. Of course, there's nothing wrong with even working for free if that's what you like, just don't make a moral principle out of it.
I don’t mean to imply it’s to get employees to accept lower pay. I mean that there is some implicit screening against people who are solely optimizing for high pay.
Lots of reasons why you would want to simultaneously pay well and not attract people who are optimizing for pay.
I don’t fully understand why you wouldn’t want to attract people who optimize pay. You always should aim for getting paid what you’re worth which is understandably hard to define. I think that’s the whole point of OPs argument how this is exploitive. You’re trying to sell a “vision” for lower pay.
