Did they get their fair share of that ‘grossly overpaying’ by Yahoo?

If they owned shares, yes. If they didn't, then why should they? The owners of the company sold the company at a massively overinflated valuation, so the shares were "worth" a lot of money. This really isn't a complicated situation.

I sort of agree with you that you can only become a billionaire by stealing someone else's money, but in this case I think your argument is kind of bad.

If Yahoo overpaid, it's not the employees of his own company that Cuban took the money from, but rather indirectly from Yahoo's employees (former and current up to that point).

I also have to say, as far as ethics goes, there is enough indirection there that unless you were a dyed in the wool communist you would have problems finding fault with it. The shell game sufficiently blurred where the capital originally came from and it looks more like winning the lottery than exploiting your employees to the people receiving the big paychecks.

Similar things can be said about venture capital recipients. They get money, and obviously it's money that the people who gave it to them did not do sufficient work for them to have gotten it themselves, but the source of that money is so convoluted that it might as well be gambling profits.

Interview with Broadcast.com's original founder who made bank, his brother who invested $2,500 made $850M and mentions his girlfriend, who also invested, made millions as well. Any employee who had shares in the company which is often the case (you really need citations for how this works?) also would have made a lot of money.
