It's not free, someone has to pay for it.
Pretty weird & ignorant post. When you talk about something being free, you talk about it being free or costing nothing from the perspective of the consumer/buyer.
That is kind of basic & you don't really need a Phd to know what the term "free" means or are people gonna come up with ridiculous new definitions to justify such posts?
He is not wrong in general terms, though.
I'd sit here and write the lengthy essay on everything from opportunity cost to what free truly means, but it would just get ignored by shadows, which is why I ignore his posts and so should you.
