A pet peeve of mine, but: "bloat" is such empty criticism. It's just repeating that one doesn't care for something, e.g. there are people who claim a tab bar in the browser is bloat and is not related to surfing the web. When people mention bloat, that usually comes down to wanting to inflate the importance of their criticism.

So in this case, the criticism comes down to: I don't like Pocket, and it's centralised. Which I don't think is very strong; the exact same point could be made about Firefox Sync: "they're pushing a bloated built-in centralised service that is very difficult to turn off entirely". Technically true, but really not a compelling argument to remove it or to make it easy to remove all mentions of Firefox Sync from the interface.
