I have been wanting for a while to make Diffractor free. It is almost free now in that the majority of users don't pay anything. Github has a sponsors feature where users who like diffractor could sponsor it instead.

Diffractor purchases are currently used to fund various costs: development tools, running the website, the code signing certificate, google maps data, etc. I do not make a living from it - I made it because I needed it.

If it becomes free, I am worried users who have paid already may feel unhappy. I am creating this issue to gather feedback.
