I see a ton of comments worriedly mentioning how this affects employees, but I don’t understand how it affects employees — can someone give an ELI5?

It sounds like they require stock owners to double the number of stocks purchased — does this mean employees with RSUs have to take part in the raise to keep their stock? Are RSUs even the right concept to think of here?

Interesting to see what the end game is here. Is the goal to prevent a hostile takeover by competitors?
