Where in the license does it forbid such a thing? Commercial use != an individual paying for third party support/service/development.
>> used for selling goods or providing services for money, rather than for personal use
(https://dictionary.cambridge.org/dictionary/english/commerci...)
An individual being paid to provide a service is commercial under that, and most legal definitions of the word.
The license only forbids third-party to offer Umbrel by themselves. If you pay for hosting, and install it on your own, it would be fine.
> Selling Umbrel, including selling cloud-hosted instances with Umbrel or its derivates, home server hardware with Umbrel or its derivates, support services for Umbrel or its derivates, etc is not permitted under our license.
There is nothing "free as in beer" that even comes close to this in polish. This is gorgeous.
