If you think that former early employees don't contribute to future "generations" of work, then the ethical thing to do is to offer better cash compensations and less equity. It's not really ethical to offer equity compensation that looks like it could be valuable but has significant hidden barriers to actually being used.

That's one of my main points: Employees have the power to refuse employers that offer equity in lieu of fair salary. But my experience has been that people keep falling for the equity carrot again and again, and as long as they keep falling for it, employers will keep doing it.
