Looks nice, but the value proposition sucks for 5 bucks a month
As far as online services go, Feedbin is absolute perfection.
They offer a clearly defined service. I give them money and they provide said service. It is rock-solid. One invoice email every month, and _absolutely nothing else_.
No changes. No feature creep. No upselling. No customer satisfaction surveys. Zero bullshit, zero annoyances. None. Zip. Zilch.
It's just something I have not encountered myself.
Their value, for now, is that they managed to push it through and actually deliver a solid product (apparently, from what the commenter said), with a sensible form of self-sustaining, so users can rely on it still existing in 3 years time. That's also itself part of the value proposition, for lots of users.
