Absolutely. This is supposed to persuade people who say they want games to be long enough to be worth their price, but the actual intention is to create an excuse to charge forever while offering very little for it. It's very easy for any game to pad out their playtime with grind.
It's yet another way to trick people into paying for trappings of games that have nothing to do with the actual content. If you buy a board game, or an oldschool game cartridge, you don't need to keep paying for it however many times you go back to it. They may use servers as another excuse, but today servers exist to enable them to charge extra, not because they are truly necessary. There are many older and smaller games, as well as Minecraft, that show that players can run online games on their own just fine.
And they charge extra by selling fiction. Shark cards with in-game currency are just a number in the game that is trivial to change with no effort from them. It's very different from selling content packs including new vehicles and weapons, locations, characters and story. Same goes for games that sell the chance of getting an unit of an item or character, split by arbitrary levels of rarity that have nothing to do with how demanding it was to create that content, rather than selling full access to content packs including those items and characters, to be used however many times they player wants.
It's layers upon layers of something that is pretty much a scam at this point. Taking advantage of people who can't tell apart product and service from a sense of hype and value in an imaginary context.
