Still, this seems to rankle people, including a bunch of Congressmen who this week sent Google a nasty letter demanding there be some kind of opt-out.
Now you can opt-out by choosing not use Google's personalized services, like its calendar and email, and simply visit YouTube and use Google Maps anonymously, that is, without using any Google log-in. Of course you forfeit some value and functionality in doing so, but that's the trade off. This also rankles people, including a the same Congressmen who this week sent Google that nasty letter.
To be momentarily charitable, it's possible that this knee-jerk reaction stems from the fact that there are certain aspects of Internet services you can opt out from, such as allowing web sites provide your email address provided to third parties. But when the grand scheme of business relationships is considered, these specific opt-outs are exceptions. Most of the time, there are some binding stipulations when you agree to use any tangible or virtual service.
A good example is non-smoking rooms at hotels. When you request a no smoking room, even if you're a smoker, the hotel's guest policy requires you to abstain from smoking in your room or face a hefty cleaning fee. You can't request the non-smoking room and "opt out" of the condition to pay a cleaning fee if you smoke.
Note the smoker is not turned away into the night. What the smoker must settle for, however, is a room where the carpet doesn't smell as fresh and the upholstery isn't as clean. To complain that this is an inconvenience doesn't get much sympathy, much less an obnoxious letter from Congress.
