Title should have [2025], since this blog is from 2025.

On subject: In 2026 I hope the wars FOSS vs OSS and copyleft vs permissive are over.

This article has a lot of nonsense. In practice you should choice a license that meets your goal. So do not choice a license from an ideology , a license has a purpose and every project has a different goal.

"This means as an author of some copyleft code, I have special rights that my users don’t have: I am allowed to use my code for proprietary purposes" -> Nonsense: Everyone has the same rights! You can not revoke a license, and re-licensing your own GPL code has more nuances than stated in this article.

For every OSI approved license is a place in 2026 and a good use case thinkable. So some more nuance in 2026 and more references to scientific studies over this subject of more than 30 years history would improve this old article.
