Müller has now published a rebuttal of the ZD Net rebuttals. His claims broadly are
- He did find proprietary Oracle code with licences altered in the Android code,
- He did find this Oracle code in more than one Android device,
- He did not claim it was in every Android device,
- The counter arguments against his discovery are largely straw men.
Müller has given links to where he found the code he considers infringing, so anyone wanting to verify his claims is able to do so.
The Oracle Android suit is about both patents and copyright. Müller is known as a software patent commentator, but Müller is only addressing the copyright issues in his post. (That's not a criticism, just an observation).
