We have so many confusions as to what "opt-out" or "opt-in" means... see it all the time in this forum and others. I suggest we get all to revert to the original terms which are "subscribe" or "unsubscribe"... but that ain't going to happen.
Me, I don't google... search engine, gmail, etc. etc. etc.
Read Robert A Heinlein's "Moon is a Harsh Mistress" or Isaac Asimov's Foundation Trilogy, or even Arthur C Clarke's shorts all the way to Rama...
The PC and that is not "politically correct" Personal Computer killed major corporation biz plans for managing all computer technology back in the very early 1980s. IBM, DEC, etc. were very disappointed and spent years trying to reacquire that control... and Google, through a back door, has managed to set sights on that acquisition, and done so with ham-handed "you are subscribed until you unsubscribe and in the meanwhile we get all your stuff" tactics.
Could go into a long rant regarding history repeating itself but won't. Folks my age (61) know the answer, those older have already lived through this and have bunched undies. Sadly, those younger have been taught the nanny state/corporation/phone company knows best.
We live in interesting times.
