O.K., so if I find an RCE in Windows 10, I have to sell it to Microsoft. But if I don't like the price I'm going to get from Microsoft, why wouldn't I just not independently find RCEs in Windows 10, and instead just sell engineering services to non-Microsoft companies who want to find and exploit those vulnerabilities themselves?
Obviously, you'd want to ban that kind of service. But how would you do that? What does that ban look like? A ban on reverse engineering? How do you differentiate the kind of reversing that Tridge did to build Samba from the kind of reversing HD Moore's team does to build Metasploit? Also: you want to ban Metasploit?
