If X gives creators money from adverts, then I don't feel like I can participate in that. It feels too much like I am being bought off, and I don't like the psychological warfare element of ads. Donations are my model — free content, produced to my own desires. Subscriptions are for when value is being delivered to a schedule of deadline. Would be lovely to have a stable and comfy income, but that's ads are how I want to get paid. A share of subscription revenue for being a contributor to the platform is OK; but then creates accounting issues about allocation and costs.
The best model is to have products or services, but none of the social media platforms have thought through how to integrate their promotion. "Ads" for my own stuff like books or art prints (with rev share to platform) are just fine!
Someone asked AU to consider a marketplace platform. It might have a membership fee but ads not necessary.
