i see what you mean on the nature of donations and the steps patrons can take if they feel unsatisfied with the benefits and stuff but i still think its essential to consider the broader context of subscription-based crowdfunding platforms like Patreon.
while its true that the benefits listed on each tier are perks and not obligations, its also important to acknowledge that these tiered benefits play a significant role in attracting patrons to pledge their support, patrons choose to subscribe and contribute because they believe in the project's potential and want to see it come to fruition, their ongoing support is not solely based on goodwill, but also on the expectation of receiving certain exclusive content or updates in return, platforms like patreon provide a structure where creators and supporters enter into a mutually beneficial arrangement. This arrangement allows creators to receive consistent funding and motivation, which is crucial for their continued development, while supporters get to be part of the creative journey and gain access to exclusive content. It is not just a one-sided act of giving money but rather a symbiotic relationship. and your right that they can just unsub, also you say donations but its subscriptions i would say that they are for expectations, hence the symbioltic relationship aspect, but i do see what you mean though
