If you read the article, the main point was that Spotify doesn’t inform about the limits clearly. Not the pricing.
Even now Spotify site says: “Spotify Premium: Listen without limits”. Clearly there is a limit, but the limits are only mentioned after the first subscription button if you scroll far enough.
