Uh, no, you can't get all games on itch.io for free, some of them have a minimum price. If you mean web games, that's been considered and rejected by the dev team (though people keep asking). And not everyone can legally make money here, or wants to.
but it can always be free, no matter the price that the game maker sets, i can make all purchases of itch.io be zero dolars as a customer, isnt that a problem? thats the one that bugs me the most, like, dont you wanna be paid, there are some major releases on this platform and they run the chance of making 0 bucks! i mean, doesnt that concern you? i have rarely encountered games with a minimum price. wow, i finally found the right words, like for real, doesnt it concern you, that people who worked their ass off run into the issue of paypal letting the customer set their price, i know it says so in the wiki, yes, these are all asking prices, yes, you can not stop piracy, people who dont want to pay will never pay, but do we have to make it that obviously easy for them? or am i able to change the price as a developer, like cant i be a dev and a player and thus pay fair prices and be urged to pay a price for owning something that someone has made and desserves a dollar for, or two or more! its not the amount, its what the creator asks for and shall receive. i think they desserve that backing from the platform.
