And the same can be said for those who would fill positions at the frontier. Then finally there is a political component; his post went viral, 100K+ users appear to agree with it, and it is further fuel to the fire for regulation, which we already know most Americans want.
Others being moved to the point of also leaving would only worsen the effect. A viral post too can worsen the effect as it's now even less likely that someone with scruples who qualifies for the position(s) will apply. And those in it primarily for the money - and couldn't care less about the morals - will happily send in their CVs after becoming aware of the post.
