The fallout has been that somebody has been let go after non-substantiated rumors about his activities at a previous employer, and now people are being pressured to leave the company and end all association with the company.
This is definitely an unjustified (based on the revealed evidence) reaction, and this is how witch hunts start.

However, for anything that implies this level of harassment, there had better be more hard evidence. Extraordinary claims require extraordinary proof.
