I've been playing mobile legend for more than 2 years, it's the best game I've ever played in my entire life

Why does Minecraft bedrock need to be paid? Like I paid for the game should I get everything for free? if I do get everything for free why is there a marketplace where I have to pay for it again? I'm ok with paid games that has some things you can pay using your real life money to obtain an cosmetic instead of grinding I'm ok with that because you can still obtain it for free. But I'm not ok with games like Call of duty and Minecraft that I paid for the game and then I have to pay it again! I can't even obtain this cosmetics by grinding in the game, there should be a way for the players to get this cosmetics, Addons for free!
