U.S. tech firms can compensate gig-workers with equity under SEC proposal

It's not entirely clear to me why gig-workers would choose to receive compensation via equity (at least from the contents of this article).

For a W-2 employee, it's appealing to have a share price locked in - when Amazon is worth 3x what it was when an employee started, the value of their stock comp goes up 3x.

Will gig workers similarly see some sort of locked in share price to really see the value from this sort of structure?
