There are "we can't please everyone" decisions, there are plain mistakes and there are UI decisions that benefit no one except possibly the company - i.e. dark patterns.

I personally don't see what benefit putting the subscription management behind an unrelated UI widget that doesn't even appear to be clickable could possibly bring to an end-user. Or how such a design got through usability testing in the first place. Hence the likelihood for a dark pattern seems pretty high to me here.
