One example is Mission Motors, an electric motorcycle startup which Apple killed off by poaching its top engineers.
Then there's A123, the small battery company whose top engineers and chemists Apple poached in order to build their
own car batteries, in violation of non-compete and trade secret agreements. Apple recently
settled out of court with them.
The biggest example that everyone knows about the way Apple dropped UK company Imagination Technologies as their GPU designer (after it helped make the iPhone popular), while hiring away all their engineers to a new Apple GPU design campus that was opened just down the road. I mean, talk about being blatant. This devastated the company so much they had to put themselves up for sale.
You're forgetting that it was Apple that tried to halt the practice of poaching engineers. One of the first things Steve Jobs did when he returned to Apple in 1997 was call up the heads of the other major tech companies and get them to agree not to hire away each other's engineers.
(Perhaps Jobs remembered how Microsoft had just hired away Claris's top OpenDoc engineers when they were developing an OpenDoc version of ClarisWorks, not because Microsoft wanted to develop something similar, but because the success of OpenDoc would have threatened Microsoft's entire Office suite business model, and Microsoft wanted to kill OpenDoc dead. Perhaps Jobs thought tech companies should compete on their own engineering merits, rather than on trying to undermine the work of their competitors. Perhaps Jobs had other reasons, but that is what he did.)
For several years, Apple succeeded in halting the practice. Then just a few years ago, the Federal government determined that Apple's non-poaching agreements with other companies were illegal, since they restricted the freedom of employees to contract their services to whomever they chose. (I forget the details, but they were reported here on MacRumors.)
As for the employee non-compete agreements to which you refer, they have long been legally unenforceable here in California.
Apple have now been placed in the position where they have been told that, whether they like it or not, their employees are legally free to shop their services around to others, and that their competitors are legally free to poach their employees.
When all of Apple's competitors are now free to poach Apple's own employees, do you really expect Apple to refrain from poaching the employees of others?
If you don't think this is a healthy way to do business, then perhaps you should direct your comments to your legislators, since they, not Apple, write the law.
(I speak only of the poaching of employees, not of the unauthorized use of trade secrets.)
