Although it would be HILARIOUS if Amazon Sues Oracle on day one after the ruling for their copying of the S3 API.
That said there are ALL KINDS of interop code that is at risk with the ruling, only people with their heads in the sand and do not understand the industry at all believe that nothing negative will come about if this ruling stands
Yes, there are parties that stand to lose a lot in the short term from a decision for Oracle.
But would it be so bad in the long term if proprietary vendor-specific protocols were put at a disadvantage? Maybe back-to-basics open protocols (or at least protocols formally contributed to the public domain) would resurge, and interoperability would actually _increase._
Oracle is a case book study if it, that is their entire business model
This isn't how the courts work and it's sad that Google has pushed this nonsense for the past 6 years.
