Rewrites happen even with PHP, once it becomes clear that their product is creaky, slow, and no one good is willing to maintain it. (To be clear, I'm sure PHP is appropriate for many situations, but I have seen people trying to dig themselves out of a slow PHP framework, and a better PHP framework isn't evaluated to be as worthwhile as moving to a different platform.) As much as some managerial types try to deny it, tools end up having an effect on the product. The skilled people they hire are often right when they try telling them that the tools aren't appropriate for the job. At least if they're experienced and provide a reasonable, fair analysis. Tools present tradeoffs. Advantages and disadvantages. Haskell can be very problematic for a business, unless you know how to deal with its disadvantages, or aren't affected by them.
