Earlier quoted context omitted.
Regulation doesn’t make unprofitable businesses exist. If the business model is unviable with support those businesses will simply not exist or cost an amount of money that is unappealing.
Nowhere has it been shown that adding support people would make these companies unprofitable.
The cost of customer support is much, much bigger than people realize. For a low-margin business, a single customer support interaction might wipe out an entire year of profit.
Even the most optimized ad-supported companies like Facebook have revenues (not profits, that's before expenses) in the range of a couple dollars per user per month. A typical ad-supported business might have profits as low as a couple pennies per user per month. A single customer support interaction that takes 5 total minutes could take years to recoup.
I know people want to speak to someone, but the reality is that they like their $0 services even more.
