I'm sure the number is fairly insignificant, especially for a company as big as Google. As for myself, I requested that all my data be deleted when I first heard rumours about the buyout, and I haven't used my Fitbit since.
I've been using it on and off since I got it a few years ago. I'll use it for a few months, then leave it for another few months. The last time I used it was from the beginning of this year 'til August. Stopped using it after that. This basically means I won't use it ever again in the future.
Your anecdotes may be relatively worthless to a company as large as Google, but they may yet be quite valuable to an individual reading your words. Don't be afraid to share your thoughts; sometimes these smaller, more human interactions can make all the difference.
