In general people seem to expect everything from devs to be free these days, as most apps you use are free, so it’s great that there’s a fixed dev share on this from day 1. If some extensions are made free of dev share, it will again set the expectation that devs don’t deserve a share in their work.
You already see some hostility from viewers (not streamers) on dev share, even though streamer share is praised to the skies.
So I’m definitely against being able to remove dev share from extensions.
