The article goes into a lot of the nuances around piracy, rather than the very specific quotes seen in the OP.
The gaming industry, and especially publishers have often, and for many years, cried about how significant piracy affects their sales. These statements often linked to reasons for not putting as much importance on the PC platform, especially in the past. Despite all of this, the PC platform, along with Mobile, are the two fastest growing platforms. Games often match their console counterparts in sales, sometimes more, or less, depending on differences in general tastes between the platforms. It was long-believed that PC users only bought at extreme discounts, but that was debunked with SteamSpy, and also showed that sales have much longer legs versus their console counterparts, which largely rely on day-one volume. Denuvo has been very successful for the first couple of months of a game's release, and thus far, I have yet to see any significant evidence of this significant problem. The burden of proof is on them to show that piracy is a significant problem, not on the other side (proving a negative).
Just like the article opens with, it's very easy to condone piracy. You should be buying your games. I most certainly do, but there are a lot of nuances to this discussion such as restrictive DRM and long-term preservation which matter to paying customers as well.
