1. I didn't read the full announcement/TOS change by auttomatic but it sounds like BS.You can't give up your copiright, you can only license it under a permissive license, and the language used is not legal enough to make any sane lawyer comfortable enough to recommend the reimplementation of auttomatic's API without getting an explicit permission first.

2. This has nothing to do with GPL as the case is about the reimplementation of API and not its use.AFAICT oracle didn't sue google for writing code that uses the API therefor even they probably agree that whatever license an API uses is not relevant to the license of the code which makes use of it. We are still waiting for the court case that will determine if RMS is right and if you have 5 lines of GPL code on your PC then all the software on your PC has to be GPL.
