Earlier quoted context omitted.
> The license forbids me to hire another vendor to service the product. That is the definition of vendor lock-in. Where in the license does it forbid such a thing? Commercial use != an individual paying for third party support/service/development.
I don't know what the intended definition of Commercial is, as it is not defined in the license, but the common definition is: >> 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.
