Wouldn't that go both ways and encourage more activism?
I wouldn't mind being an activist employee if I know that not only do I stand up for what I believe in, but there's a reasonable chance it will result in enough compensation for an early retirement. I'm sure I'm not the only one.
I wouldn't do it without caution and it does require funds on my end, but I'd still do it. That said, Amazon will likely engage in prolonged litigation, to minimize the benefits.
