Uh, no. Hard no. Literally any legal principle in which Google has to pay for 20 lines of API declarations (which is the thing that Oracle was able to claim copyright over in court) means pretty much the end of software freedom, since reimplementation is how FOSS was bootstrapped. This means that Microsoft could sue Valve for offering Proton on the Steam Deck. GNU and BSD become legally radioactive. Ruffle survives only through detrimental reliance[0]. The entire console emulation community gets sued for hilariously large sums.

Oh, and Oracle now has to pay billions of dollars to Amazon for providing an S3-compatible storage API, completely ending their cloud ambitions and cementing the AWS monopoly.

[0] Adobe published documentation on SWF specifically to encourage browser vendors to reimplement.

I think Google should have bought Sun when they could. But whatever your opinion on that case is, my point is that copyright is complex and has big grey areas, and having to fight this out in court is going to be way too expensive and risky for most parties involved.
