Time is money is opportunity cost though. If a proprietary provider is able to get you up and running faster then that's more time you have to spend on other things, like the rest of the business. Let's be real, the chances of getting shutdown if you're not in a grey area is pretty slim - if you are, eg crypto, porn, cannabis; then I'd not use a proprietary provider - what is "beat" is time spent on the product instead of upgrading WordPress plugins.
