The Mozilla Corporation is wholly owned by the Mozilla Foundation and bound by its charter. The split structure is an artifact of corpotations being better-understood legal entities than foundations, and thus easier to deal with in various situations (hiring, contracts, etc).

What happened with Pocket?

It was forced into FF as a non-removable extension.

After Mozilla bought Pocket.

No, two years after.

The integration happened in 2015. The acquisition was not until 2017.

They have some history of selling out their users... by literally selling their history: https://blog.mozilla.org/press-uk/2017/10/06/testing-cliqz-i...

This was an experiment (2017), not sure what became of it.

> Less than one percent of users in Germany installing Firefox from our main download page will receive a version of Firefox with Cliqz recommendations enabled out of the box.

> This experiment also includes the data collection tool Cliqz uses to build its recommendation engine. Users who receive a version of Firefox with Cliqz will have their browsing activity sent to Cliqz servers, including the URLs of pages they visit. Cliqz uses several techniques to attempt to remove sensitive information from this browsing data before it is sent from Firefox. Cliqz does not build browsing profiles for individual users and discards the user’s IP address once the data is collected.
