In this hypothetical scenario the real money might be in consultancy. "Sure, we can get your organisation set up with OpenNotAWSBecauseTrademarks. Our rates are $20K/consultant/week and we expect to bring a team of 5 for a fortnight." It just has to be a comparable cost and financial structure to how a large organisation trying to escape from cloud lock-in would have otherwise expected to engage their cloud architecture consultants or cloud security red team or other cloud specialists and then you're in the game.
Technology is a good business because a small labor input can scale to a very large impact. I'm sure there is a place for consultancy but I don't see it winning against "scale" in the long term.
