Why not? It is basically a public domain license, it just uses more colorful language. IANAL, but I see no problem using such code in corporate environment. What are the risks?
If you are operating internationally (like nearly the entire tech industry), complying in as many jurisdictions as possible is very valuable
Also, in a corporate environment, there's typically some additional overhead cost and bureaucracy and approvals that a new license text brings in, even when the engineers and lawyers manage to agree everything is OK.
Which is a problem.
