This is a valid concern, it's kind of icky to open Firefox and see them pushing some company Pocket's services.
Inspired to research further, I looked and found that Mozilla acquired Pocket in 2017, and it supposedly works on your local-only data for recommendations. Pocket has a subscription plan, and Mozilla as a free software co doesn't have many revenue streams. Them needing to present their product to users doesn't seem that bad viewed in the context of needing a way to support the product. I do think it could be better presented ie explained clearly what pocket is and why they show it to us.
