Yes, many in fact. We negotiated the terms up front and if I didn't like them then I went with another offering company. I never had deals change from under me, maybe you're some Eduardo Saverin but I'm not. That you got screwed for not doing your due diligence doesn't mean everyone does. I'm not sure what is immoral, unethical, or unfair about that when again no one is forcing you to work at any particular company or even startups, or even in the tech industry. There are lots of jobs you can do.
Ultimately it's possible to get screwed, but you can also choose not to work at startups and get a traditional job with less risk.
And the existence of some bad actors and screwy deals in the startup community is not really valid commentary on the greater picture of "the way wealth is shared." That was one way that wealth was shared, at one company, in one industry, with one or several bad actors.
Just to be clear, we're talking about the same LLMs that were recently silently tuned to kneecap competitors? https://www.wired.com/story/anthropic-responds-to-backlash-o...
Except it's not. It's the norm not the exception. It's pervasive through the industry, and YC and pg have done it themselves to multiple companies.
Hence why it was literally turned into a meme plot on a TV show.
You also ignored the bit about the negotiation being inherently unfair from the get go. And again, the deal can (and almost assuredly will) change out from under you because of the structure of the company which isn't really up for negotiation.
