I certainly get the hurt feelings, but i'm not clear on the license at all.
>Limitations: You may not provide the Software as a hosted or managed service that offers users access to substantial features or functionality.
Where on the spectrum sits an average cookie-cutter VPS provider that comes with an OS package manager that installs the program? Does the VPS provider have to screen the package manager? Does that change if they build a wiki with "1-click-install" that just sends an ssh command to install?
Is this just a requirement to have some theater where an "unaffiliated" third party has to provide the set-up scripts? Or just a rule you can't mention the option during the sales pipeline?
I think users applies to end-users here. So you must not run the software as a service (either paid or for free) for other users. You are free to use it yourself.
Crucially, I think what is banned to offer accounts. Offering turnkey-hosting is probably banned in spirit, but the person offering the turnkey-hosting is not in violation, rather the person booking the turnkey hosting and offering the accounts on the instance to third parties is in violation.
I think the wording is originally against somebody like Amazon hosting e.g. database instances for other people to use, and then giving you an account in that database. It's still OK to rent a VM from them and use the package manager to install it.
In any way, it is really confusing, in a way a license should not be. And I don't really understand why someone builds a blog platform, which is not monetized, open sources it, but doesn't want other people to host it. If I open source my stuff, I want people to use it. If I want to share the code but don't want people to use it I'd just put it somewhere it with no license at all (all rights reserved).
