For ease of reading, the investigation he refers to:

In short: fake artists with stock music (changing labels and other camouflage applied). Likely goal: to depreciate streaming counts for actual artists and increase profit margins.

What I uncovered was an elaborate internal program. Spotify, I discovered, not only has partnerships with a web of production companies, which, as one former employee put it, provide Spotify with “music we benefited from financially,” but also a team of employees working to seed these tracks on playlists across the platform. In doing so, they are effectively working to grow the percentage of total streams of music that is cheaper for the platform. The program’s name: Perfect Fit Content (PFC). The PFC program raises troubling prospects for working musicians. Some face the possibility of losing out on crucial income by having their tracks passed over for playlist placement or replaced in favor of PFC; others, who record PFC music themselves, must often give up control of certain royalty rights that, if a track becomes popular, could be highly lucrative. But it also raises worrying questions for all of us who listen to music. It puts forth an image of a future in which—as streaming services push music further into the background, and normalize anonymous, low-cost playlist filler—the relationship between listener and artist might be severed completely.
