I think, obviously, there's an element of sensationalism to the story ("Someone is getting rich on their hobby! And they don't make a product!"), but I wonder for all the ads on Roll20 and DDB how successful they are. As was pointed out, you have to get solid people into the game, and have something they want or need to come back for.
There's always been a disproportionate number of players
M - the game is set up that way, one person running it and X players. Now that there's the internet available, I think people who may not live in reasonable distance of a gaming store, or don't like the people there, or have the spare money to invest in another session (another fix?) would probably content to pay $5+ for the opportunity. As a person who would DM and then burn out - I'm a frantic idea guy and my ideas don't always stick - I couldn't imagine doing this for a job or even a side hustle.
I did/do see a post I like on reddit and Roll20 where the DM explains why he charges, and I think his number one point felt the truest: if someone pays for an event, you are way less likely to ghost on it, you're more apt to have decided to commit to it, and you're probably apt to get a more commited group of people who want to be there versus people who have nothing better to do.
