A couple of thoughts:

I believe that there aren't enough customers for these services at the moment.

However, I still think this is a necessary innovation. Products like these make the liquidity challenges of Lightning more manageable. Imagine a merchant who is on the fence and is debating whether to implement LN. A product like Hydro nudges the merchant closer to implementing LN. Likely, it is still not enough, but in any case, it moves the potential customer a step closer.

So kudos to Amboss!

And all os us need to keep building.
