Yeah, this is it exactly. There are definitely valid criticisms of this kind of tool, but people need to understand that there are already a lot of small, niche creators doing this kind of thing manually, e.g. by accepting PayPal and manually emailing Google Drive links to purchasers.

These people obviously don't care much about piracy (and probably don't need to, either) and don't seem interested in setting up another service like Gumroad/Patreon/OnlyFans, so being able to trivially automate their existing manual processes sounds pretty handy.
