Now I wouldn't go far as to say that they don't care about their games, though I do agree that money is the primary goal. We've already know that Pokémon makes a ton of money from the merchandise-
see here. As we can see, the merchandise makes the most of the money-the games actually make significantly less money when compared to merchandising. This goes back to the games featuring and introducing brand new Pokemon, as well as new forms of Kanto- People will buy them off nostalgia-
I looked up Charizard on the Pokemon Center and found 30 pages worth of results-
I looked up Salamence and only found 3 results. Of course, it also has something to do with GF constantly putting Charizard everywhere- which brings up a second point: Pokemon is so rich to the point that GameFreak could just retire and give up the franchise to some other company. In fact, if anything, the games can be considered a leisure project, in other words they can do whatever they want. Even if SwSh were to fail, it would not doom the Pokemon Franchise- merchandise from based on SwSh would undoutbly sell, powering up the revenue of main money merchandise. They aren't listening to fans or putting more effort because they don't have to, as the guy concludes, the majority of Pokemon sales comes from the merchandising. In contrast, if you look at Mario- most of its money comes from video games, that's why games like Odyssey had to step up mechanics, gameplay, and graphics significantly- A super Mario game failing would significantly hurt more than a Pokemon game failing for there respective franchise.
