It will backfire if they don't do something nobody has ever done?

How does that work?

I think you mean that Trump people will get mad at them for highlighted his screwup. I'm sure that's true -- they've decided to back Trump no matter what, which leads them to numerous irrational positions -- but it's not like Amazon or anyone else can do anything about it. Trump and his supporters just thrash about destructively and we all pay the price.
