If it's effectively opt-in, it's hard to argue that this is Mozilla "willing to sacrifice their user's privacy and security" and that "telling Pocket what they read" was "shoved on everyone", if in fact it is a choice to have your browsing history sent to Mozilla.
Replacing a privacy compatible feature with a revenue generating privacy incompatible sacrificed privacy for revenue. And what you called the implication was your inference.
