Dislike of a particular aspect of a product doesn't need to be concrete/provable - a vague feeling of "I don't like this so I won't use it" is all it takes.

With Pocket in particular, the bundling with Firefox moved my impression of it from "this is a potentially useful tool" to "this company feels like they need to force their product down my throat by bundling it with a browser - I don't know why they're doing that but it makes me not want to keep any data with them"
