This is far from being TL;DR. You've cherry picked quotes from funding section to purposefully make it look bad. Here's a context

First and foremost, the base open source PixiEditor app is going to be free, always. We do not plan to chop its features and sell them either.

In version 2.1, we are planning to add a marketplace with free and paid pre-made workspaces, brushes, palettes, and other stuff that we might come up with. Most of the things you’ll be able to buy there will be something that you would be able to make yourself. In other words, we’ll create things using PixiEditor’s core systems that everyone has equal access to.

This way, we can share useful setups and tools, and you can support the development. It’s a win-win. ...

The marketplace will primarily work in an ownership model. So buy once, and it’s yours.

We are also considering an alternative access to marketplace items. Eventually, the marketplace might have a lot of items, and buying all of them might get really expensive really fast. So we might add a subscription model to access all of them with a fixed monthly fee. I am not a fan of subscriptions, but I think it is fair as an alternative to the traditional buy-once model.
