The vast majority of people doing creative work that you enjoy largely for free are making barely enough to survive off of it, or doing it as a "labor of love".
For years people said "oh if only there was some way to pay the content creators directly!" now with Patreon there is.
Most software engineers have no problem dropping $20 on a four pack of nice beer, but can't be bothered to pay $5 to watch more of a video they already spend 20 min watching for free? With the added bonus that you are supporting the creation of more content you like?
It's not a big deal if you don't want to buy the product, but to complain that it's something you have to buy is absurd.
