I&#x27;d encourage you to keep the opt-out setting as-is. It clearly brings value to the development team, you&#x27;re communicating it to users, and Homebrew users who aren&#x27;t comfortable with opt-out can a) disable analytics or b) not use Homebrew. Switching to opt-in is going to greatly diminish the dataset you&#x27;d have for making improvements (selection bias).<p>The Homebrew developers&#x27; time is valuable, versus a subset of users making demands of a free tool. You&#x27;ve been conservative in how clients are identified, as well as the data collected, and people are still suggesting unreasonable alternatives. Can&#x27;t make everyone happy. Thanks for an awesome tool.
