Oh yes, the "poor" rich people being threatened by the actual poor. Very threatening indeed.
If a large tech company wants to thrive in a particular area they should make sure they don't alienate any groups already existing in that area to the extent that they feel the need to wake up early in the morning to go and throw rocks to get their attention.
If it gets to this point, the company should do something to try to address the issue, and any employee that genuinely feels threatened should refuse to work until their employer provides a safe working environment.
