I completely agree with that. A paying user equals responsibility. My point isn’t to make paid plugins the new standard. I’m talking about having the ability to easily make paid plugins.
This would give Kirby the ability to grow further. I’m not talking about turning into a WordPress type of mess, though. But nowadays, you have web services for everything and it’s expected to have the ability to integrate those services into everything. Due to Kirby’s flexibility, integrations for third party services can be very versatile. The problem is - someone needs to develop them and support them. Since nobody would do that for free, Kirby needs to figure out a way to allow that to happen.
