"I don't even run a business, I am just a freelancer, but I'd happily pay 600 USD/year for this service if I needed it." Yes, you do run a business, yourself.

"I don't even run a business, I am just a freelancer, but I'd happily pay 600 USD/year for this service if I needed it." Yes, you do run a business, yourself. But outside that... The problem with this sort of thinking is that, yes, sure, if you need it, you could happily pay $600/year for this service, and another, and another, and another, and pretty soon you're dropping $5-$10k on services. For a large business, that's probably not an issue (but even then, it's always out of someone's budget, not the entire company's), but for smaller companies, you're approaching a pain threshold.
