Yes, it's the approach and principle of the interaction. If {{software}} asked to opt-in to collect anonymized/generic information, for what purpose(s), and how it was being stored/anonymized to "vote" for feature use/maintenance and how it was definitely not going being used, like not being sold to data-brokers, then I might say "yes".
