So you're telling me they have an entire company, dedicated to only one game, putting in minimal effort and not really worried about their sole product? C'mon...
What I see is a complicated market, where racing games are more niche and are finding it harder and harder to justify the large investment made to release new games.
Most successful attempt recently either go light on content, and hardcore on experience, and focus on PC gamers, to cater to more sim-racing minded folks; or really broad in gameplay style, adding more variety, like the Forza series expanding to Horizon, which did massively well, and outshine Motorsport, catering to the masses, and deliver a good console experience.
GT is caught in the middle - it speaks to the more car loving and "simcade" audience, but it can't really go full beans into sim-racing, not without alienating the vast majority of PS owners, or sacrificing the amount of content offered.
They have tried several different approaches. They were going all in on GT Academy, and later made a lot of investment in eSports with GT Sports, which didn't offer a good enough return on investment for them to fully rely on that. They scaled back their investments in World Tour, reduced their worldwide sponsorship of different drivers, namely Igor Fraga on F3 (now more Japan-based, on GT 300 and Super Formula Lights).
With GT7, the attempt seems to have been more focused on creating a live-service type of in-game economy, which fortunately, failed massively. It's safe to assume that it made a huge dent into their longer-term planning for the game, however. Hopefully, their brand partnerships and in-game activations (think Michelin, Porsche, and especially Toyota, Mazda, Subaru) are somewhat compensating for that.
Finally, we now have the movie, which takes the messaging around the GT brand back to eSports and GT Academy. Hopefully the Barbieheimer craze passes in time for the film's release in a couple weeks, and the hype behind F1 and motorsports in general, helps push its popularity.
Either way, they are desperately trying to find avenues to market and monetize the game in a way that's appealing and financially viable, which is increasingly tough nowadays.
