However, I now have no direct imperative to financially support some orgs/projects I like (GreenNet, Wallabag, etc).
I could self-host and donate, but then it probably ends up costing more if you factor in time and money combined.
I wonder if the purity of 'self-host everything' goes a little too far.
I think perhaps my preferred middle ground would be ownership of data, and remunerating orgs I like to provide apps that operate on that data.
The Personal data store approach.
