While I can see the fun and useful part in collecting this kind of data ("80% of our users use the 'high' setting - let´s improve Gen 2 on that point"), I think more and more companies are losing track of what´s "good and bad" for the sole purpose of improving products. Why not directly ask the customers, make an opt-in or whatever, instead of anonymously collecting this kind of data from everybody. Come on, in the end it´s quite private after all.
