I prefer to provide only pre-programmed chips (with CP fuse blown), or to provide the code to a third-party burning service who is put under a NDA to keep the code from the customer. The source code goes to a lawyer who puts the files in an "escrow" account, to be delivered to the customer in 5 years or we go out of business. It all depends on the customer, though. Some get source with no restrictions.
