Wow, that's one of the worst-written articles I've seen in a while. It almost feels like a comment on something that we aren't shown. Almost every sentence is missing essential context. When did he say that? In what context? Can we get a direct quote?
That being said, the head of one of the biggest console manufacturers and gaming publishers in the world blaming capitalism for the state of gaming is a true selfawarewolf.
Edit: PC Gamer has an article that's a bit more readable. Seems like Spencer sees the problem (investors value growth over everything else) and goes to the wrong conclusion (he needs to find a new way to grow his department).
The real problem is greed. These days, it's not enough for a business to be profitable. For the guys on Wall Street, it needs to be even more profitable than last year. That goes so far that an old employer of mine complained not that they had lost money, not that they had not grown but that they had grown less than the year before and therefore all teams had to cut down on spending. To them, everything less than exponential growth is unacceptable and nobody even considers that the market is finite.
