Unsurprisingly, it's likely that this "death threats" situation was made up by the ceo: https://www.reddit.com/r/gamedev/comments/16j21jg/the_truth_behind_the_unity_death_threats/

It's a reddit link, ik... here's a copy of the post:

The truth behind the Unity "Death Threats"

Unity has temporarily closed its offices in San Francisco and Austin, Texas and canceled a town hall meeting after receiving death threats, according to Bloomberg.

Multiple news outlets are reporting on this story, yet Polygon seems to be the only one that actually bothered to investigate the claims.

Checking with both Police and FBI, they have only acknowledged 1 single threat, from a Unity employee, to their boss over social media. Despite this their CEO decided to use it as an excuse to close edit:~~all~~ 2 of their offices and cancel planned town hall meetings. Here is the article update from Polygon:

Update: San Francisco police told Polygon that officers responded to Unity's San Francisco office "regarding a threats incident." A "reporting party" told police that "an employee made a threat towards his employer using social media." The employee that made the threat works in an office outside of California, according to the police statement.

Polygon also contacted Police in the other cities and also the FBI, this was the only reported death threat against Unity that anyone knew of.

This is increasingly looking like the CEO is throwing a pity party and he's trying to trick us all into coming.
