Kopano Groupware

[marclaporte]

Kopano was once Open Source (A fork of Zarafa)
https://github.com/Kopano-dev/kopano-core/blob/master/AGPL-3

But:

"We hereby announce the official End-Of-Life (EOL) date of Kopano Groupware to be the 31st of March 2025."
"This announcement is only applicable to Kopano Groupware, not it’s successor product Kopano Cloud, which is available in various forms for different market segments"

This is not really a rugpull/relicensing. Simply said the old code base is being retired and the new code base was never open source in the first place.

I used Zarafa in the past and I was impressed by the breadth of features and the high-quality documentation.

"The completely new code base has been under development since 2019. It is based on the know-how and experience of around 20 years of groupware development (Connectux, exchange4linux, Zarafa, Kopano)."

"completely new code base" means they would reuse none of the previous code (which was AGPL). I find it very surprising. I can believe they would rewrite some parts but "completely" means 100% and I don't understand why some parts of the code would not still be relevant.

Is this what happened (and you don't consider it a rug pull) or is it something else that happened?

1. Use our great Open Source system. Join the community.
2. We changed the name of the software but it's still great and Open Source
3. We built a new system. Not Open Source but it's still great, and you can continue to use the Open Source version.
4. The Open Source version is discontinued. But we thought of you. You can easily migrate to our new proprietary system
