It's just a form of a bitcoin exchange integrated with coupon clipping.
With a good UX, it makes for a better exchange.
But it does not directly contribute to the parallel Bitcoin ecosystem. Might be even competing against it.
Trading censorship resistance and poor ux for discounts and good UX.
Somehow I feel, that spending via these routes do not inflict change. Everyone can go on their own route, not changing anything.
But also questionable if it is bad. I guess personal goal is the question.
For me somehow these do not seem good ways to spend bitcoin. I mean if you want spend bitcoin to just spend it, it is fine. If you spend bitcoin to spread, it will not really cut it.
