It's not important what it is. Pocket was bought overpriced by Mozillas incompetent officers on a project to diversify their income by playing VC. They then decided to piss all over their Firefox browser users by forcefully integrating it with the browser. It was a terrible decision, a terrible business, and now way past its best by date its finally taken out to pasture. Sadly the incompetent officers continue their tenure and soon we'll write this obituary for Mozilla, as their C-level compensation inevitably outstrips what Google is willing to pay for a 1% market share and declining browser.

I know that, I want to determine the level of incompetence.

A page saving service is one thing, adding a curation/discovery team (paid by the subscriptions or by the sites who want to get on that curated list?) on top of that is another.
