Yes, of course it depends a lot on context. I've never had an incentive to read the Linux kernel code. I routinely find and disclosed cryptography library bugs, though usually mostly hobby projects like the "I thought it would be cool if there was a PHP implementation of GHASH" sort rather than like OpenSSL.
