alt Hacker News> an IT company that wants to resell the (free) version of Mattermost software and is now complaining that they have to pay?
A user that was following the letter of the license and has suddenly had their access to the software restricted without warning.
Open source software means people are entirely within their rights to sell it to others, perhaps creating value by providing the warranty that all licenses expressly disclaim.
I'm aware of what open source software is.
And there are 3 things that you can do when in this situation:
1) Pay the fee, if that is what is required for it to continue to be easy for you to re-sell the software.
2) Fork the project, remove the restrictions, and maintain it yourself.
3) Stop using the software.
All of those are perfectly within the spirit of FOSS.
