Mozilla claims that they don't get money for the integration, and I don't see a good reason why I shouldn't believe them. Pocket very likely doesn't have that much money lying around, compared to Mozillas budget.
its sounds a lot more like the situation was "Pocket was friends with some guys at mozilla, and they made up a bunch of bullshit about how it was a benefit to users to push their buddies project"
"Mozilla bundles crapware for financial gain" v. "Mozilla bundles crapware without any financial incentive" is a more accurate comparison, and highlights that something is indeed wonky over in Mozillaland.
Yes, but Pocket is integrated with Firefox. Pocket and the Mozilla Foundation formed a partnership that almost certainly includes some sort of compensation or resources in exchange for Pocket's service.
