Because I've had a few jobs working on products produced by recently-acquired startups I get where it's coming from but also why it doesn't make sense: those startups cashed out by making a product that was so inefficient that the numbers weren't even necessarily on the right side of the ledger. But no matter because they teed up the clients and coming back and optimizing a successful product (even if that means wholesale replacing all or part of the underlying systems) is easier than conjuring a customer base from zero.
