Appreciate the feedback @Stephen. At the moment, ALL the data that we collect is valuable and actionable. We put a lot of thinking to make sure we only collect the "minimum viable data", there are use-cases for all, we don't collect it for the sake of collection.

Here're two common scenarios why email collection is very useful for you and your users:

1) Let's assume that you mistakenly release a plugin version with major security leak. Since you are a responsible developer, you immediately patch it and release a new version to the repo. Unfortunately, it takes time till your users will all upgrade to the secure and patched version. BUT, with Freemius, you'll be able to see all the users who are still using the vulnerable version and send them an email to encourage them to upgrade. You'll be their hero, and they will be thankful for you taking care of them.

2) As you read, Freemius Insights adds "Deactivation Feedback Form". Let's assume that 10% of the users who abandon your plugin do it since you don't have featureX. Since you are customer feedback driven developer, you develop that feature to stop losing those 10% of users every day. Now, you can email all this hundreds/thousands of users who abandoned your plugin because of featureX to try and win them back. Not only that you'll win some of them back, but you are also a hero since you listened to your users and made the extra mile to implement it and engaged with followup after it's ready.

With regards to the webhook, it's in the responsibility of the developer what he does with the webhooks. But we'll do our best to educate about do-s and don't-s, and best practices, to prevent any legal violations.
