Yeah. What if someone had said "Wait, is this sustainable?" before building up a docker-based solution that. (I wonder if we can find any archived discussions wondering that, or if we're just so used to thinking "things can scale for free indefinitely on the internet" that nobody wondered?)

Now that they have it, the cost they are willing to pay is based in part on cost-of-switching. Which is pretty enormous, directly and indirectly, when entire ecosystems based on docker have been iterated.
