I agree with preferring the opt-out by default. My initial reaction to any opt-in default is to opt-out immediately and worry about why later if at all.

To further anonymize the data and increase user comfort, cycle the selected users daily so the same user's telemetry is not collected multiple days in a row. That limiting of data collection may also make it more acceptable to some users. For example, it may be more acceptable if telemetry data were collected no more frequently than one day per month or one day per two weeks.

We're definitely taking a close look at how folks will decide to participate (or not participate). As much as possible, we de-identify the data we’re gathering through this project. This data will help us prioritize our overall efforts for our customers. We are not looking to analyze data on individual users. - Ben, 1Password
