I would describe it as "Restricted use" software which has existed for decades, generally as closed source. Sure the SaaS server licenses are more or less open use with caveat, but why won't a process paralleling tivoization occur? I wouldn't find it odd for a hardware vendor to release source code, "for review" without the rights to use it on any other hardware as some do for binaries. In a way that could be worse than closed source as that is similar to the problem of suspicion of reading leaked source code, maybe you are tainted and can't actually write software licensable for competing hardware. Maybe you never read the code yet it will appear that way, but you shouldn't check. Given the oddities of IP and copyright infringement, it is often the case that only the owner benefits from a process of publishing. I.e. what good is the disclosure of a modern patent?
