I think it’s “handy” in that a win against them that forces them to admit their “contractors” are really employees – and their mistakes, like accidents that kill people, is the responsibility of Amazon – would make any smaller company using those shady practices fall in line. Maybe. IANAL.
History seems to agree that rich people don’t become rich people by being good people, and Jeff Bezos is riiiiiich.
If there’s a corner Amazon can cut, and nobody is watching them, they will cut that sucker. Like a pimp.
