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.
"In Internet culture, the 1% rule is a rule of thumb pertaining to participation in an internet community, stating that only 1% of the users of a website actively create new content, while the other 99% of the participants only lurk. Variants include the 1–9–90 rule (sometimes 90–9–1 principle or the 89:10:1 ratio),[1] which states that in a collaborative website such as a wiki, 90% of the participants of a community only view content, 9% of the participants edit content, and 1% of the participants actively create new content."
