I'm not sure about it either; it's a bit speculative. To some extent, it depends how many people are involved with Steemit or a similar platform, and therefore, how invisible they feel while doing it.

A supporting point which I didn't mention in the article is that, it's easy enough to discover who (or which Internet connection) is leeching or seeding a torrent, but in many countries, people have no bones about it, even where it's considered illegal. Piracy authorities don't have the resources to investigate everyone, and neither do tax authorities.
