As this gets more common, I think it will eventually lead to startups having a hard time attracting talent with lucrative equity compensation. It will be interesting to see how long it takes until this catches on among employees, but I already wouldn't take any positions in startups with a significant payment in equity anymore. The chances are slim that this pays out anyways, but now even when you are successful, noone will stop some megacorp from just buying the product and key employees and leaving everyone else with their stake in the dust.
