It is very hard for small startups to offer something comparable to 200k salary and 200k a year in RSUs.
But if those packages are now worth 200/70, maybe a salary of 200k and stock options that might be worth a couple million look more more appealing, especially if someone is tired of a big company.
I have a few friends who have expressed this. They wanted to leave the bigcos, but felt like they couldn't because of the money they'd be walking away from. Now they said they're looking at fun startups since their Bigco stock grant is worth so much less.
