Thank you. You bring up a great point, namely that there is no alternative except for "don't use this part of the universe at all". I think that's a problem.
While I agree this is distasteful, and I hate the companies are doing this...I have to say, it isn't the worst thing in the world to say I won't use this.
It isn't like we're talking life/death here, just a loss of a newly discovered convenience. I mean, what did people actually do back in the dark ages, before Fitbit or cell phones? How did they ever manage to exercise and track their progress? Hmm....
Seriously, while these things might be nice, you have to decide if it is worth your trading in your privacy info for God knows what purposes it may be repurposed into?
I generally vote no on things like this, and my quality of life hasn't degraded to any extent I can measure.
