Nioh is the most successful Toei Tecmo game, Persona 5 I take it one of the most successful for Atlus. Resident Evil 7 will be one of the most successful coop-less Capcom games. Nier and Crash Bandicoot shattered all expectations.
There's every chance you add all SKUs of every one of those games together and that number won't reach the highest selling (all online obviously) games of the year across all their SKUs- Battlefront 2, CoD, Ghost Recon Wildlands, Destiny 2, PUBG etc. That's what EA and the others will be after, the gravy train,
all of the money, microtransactions and all. Yakuza whatever, Persona 5 and Nioh aren't a blip on the radar of the people who make these decisions relevant to the article.
Heck even your highest selling game you've listed, Resident Evil 7, is proof that going full single player is a detriment to sales. It's underperforming, massively down from its predecessors and has really lacklustre post launch sales, matching what we've know for years that these games are used significantly in renting/borrowing/binging (dunno what the video game term is for that) over a weekend and then flooding the preowned matket. As far as single player games go too as much as you probably don't like hearing it, most of the most successful are not linear- BoTW, Horizon, Souls, FFXV, Mario Odyssey, Ubisoft's many open world games etc.
So yeah I don't think the article and the overall point is nonsense, there's far more emphasis on multiplayer and non-linearity nowadays than single player, even seen with Nintendo with their last couple of successful new IPs (Splatoon and ARMS).
But hey there is obviously light at the end of the tunnel, those games you listed were successful and are probably going to get sequels.
They're not dying, but they're clearly not the focus of the industry, or at the very least the people at EA, one of the biggest publishers in the industry. It is foolish to believe otherwise at this point.
