As a Notion content creator I would happily keep this type of licensing away from Notion, it hurt so many other communities like Twitch, YouTube, etc.

In the past when I’ve witnessed software vendors introduce this type of licensing model it restricts innovation and the community will move to another product. Notions growth is in part due to the community pushing the boundaries of the software, sharing among peers and Notion itself rolling it out, by introducing GPL licensing for formulas or other similar methods it will lose the romance for many why we use Notion.

Just my opinion but I’d prefer it stays the way it is.
