1. Mammoth organizations like this have very robust monitoring and security measures in place. You could do it, but you’ll almost definitely get caught. 2. The tech eco system of these organizations is probably so vast and has so many layers of abstraction that one developer sharing the 1% of the code base they have access to wouldn’t be very valuable to any on the outside. 3. The exception to this would be code considered to be intellectual property. in this case I’m sure it does happen from time to time, but they aren’t dumping that on the internet for all to see. A competitor is paying the FB or Google employee to take that kind of risk so they can gain advantage in the market place. These are behind the scenes deals we will likely never hear about, unless they are successful and implemented sloppy enough that the org owning the IP recognizes it in their competitors product and sues.
