For what it's worth, "prevent them from earning a living in their chosen career" is not the same as "ostracize them from all society."

A person who has been cut from a grad school program for rampant academic honor code violations can be a perfectly-functional member of society, and if no school wants to trust them as a teacher, that's not the fault of the schools.

Personally, I don't have a high opinion of the tech culture though, and I suspect even the people fired for sexual harassment will be employed in another tech company within six months. The money flows too fast and too loose to expect otherwise, and the overall engineer-owner-capitalist-America ecosystem doesn't act as a sufficient deterrent to toxic sexual harassment culture to expect these employees will actually be cut out of the loop. It's a Hollywood environment.
