What exactly are you referring to? My opinion why per posting funding is not favored on patreon? That is based on observation and my own spending habits.
My point is, that calling it a subscription when talking about creation of a game, is not quite the right mindset. You subscribe to netflix or your newspaper. But you fund/support/finance/patronize the developer. Sometimes because you want the perks or just because you like the game to be made.
Itch is optimized for projects and their distribution including paying for them - once. Not for continous creator support.
With all the linking they allow to such support platforms, itch would do good to take a share of the cake. There are many that would rather give money to itch, than to patreon. While games do constitute a large portion of patreons, the nerds of wikipedia do not even mention games in their introduction paragraph about patreon.
It is patreaon that takes away those early access customers from itch&co. Itch should take them back to a games orientated platform. Patreon is a bad company with questionable policies. I remember how they unilaterally changed their pricing some years ago, losing many patrons. https://www.polygon.com/2017/12/13/16773142/patreon-service-fee-community-backla... before reality cought up to them and they backtracked. They are not popular because they are good, they are popular, because they are big and have not much competition.
Just look where game creators go: to patreon, a non game optimised platform. They should go to itch, a platform dedicated to support indie game creators. While people whine and complain about tag searching on itch, where is the game search on patreon, like, at all?!
