I think for a lot of companies that would be an instant turn-off, especially if they're still starting up. It is very much the Silicon Valley mentality that all value is added by that company and that no suppliers should make any profit.

Apple for example likes to become a critical customer for any supplier, then use their leverage to squeeze them.
