I worked for a company that had an expensive San Jose lease during the .com bubble. When they decided they needed to get out of that lease, they folded the company - “fired” everyone, then re-hired everyone under an independent second company that was owned by the parent company. Sketchy, but not really surprising…

When they re-hired me, they didn’t have me sign any NDAs. All the old NDAs were with the company that folded, not the parent company. Some days I wish I had been unethical enough to sell off their source code to a competitor.
