Wildbow is amazing. Her "Worm" series is literally 20 full novels sized, and works like this are (or was? read it many years ago) free competition to any would-be writer who would want to require - as the article suggests - $5 per chapter of an unfinished novel. I mean, all these Patreon examples illustrate that it definitely can work, but IMHO it's more accurate to treat it as "patron" sponsorship/charity/support out of goodwill, instead of as actual economic sales of scarce product.
I love that Wildbow writes the female point of view that you assumed he was a she (assuming that wasn't a typo). He's still going strong--current work is Pale (https://palewebserial.wordpress.com/about/) which I can highly recommend.
