Let sleeping dogs lies fellas.  Speculatively, If Google is involved in any way dont want to upset the elephant. Remember how brutal Apple treated its potential suppliers if any leaks under NDAs were suspected. Its possible again, the guy was  being stalked by too many on this issue and wants to be left alone so deleted reference to POET on his Linked In. However if he is reading posts here, likely regrets doing it that way as its causing more questions amongst us. 

Either way lets wait and see and not bother our friend Ed.
