Most corporate owned devices are managed with some kind of tool (for restricting what users can do, pushing out software and updates, etc). These tools are called Mobile Device Management (MDM).
The developer is detecting the presence of MDM tools and using that to present a splash page to the user about the licensing requirements etc.
Some educational institutes use MDM to manage students, even so far as to require it be installed on personal owned devices. The developer has been working with edu users to except them.













I agree with you as I’m an old FOSS beard - we wouldn’t have gotten here without GPL/MIT/BSD etc.
But things aren’t working for a huge number of projects. And is it right that so many critical dependencies are maintained by so few with so little resources, if any? Just look at the xz fiasco we narrowly avoided catastrophe over.
The Linux Foundation is a good model for core infrastructure and projects that underpin the ecosystem like the kernel - LF are turning over $300M or something a year.
But for smaller projects that aren’t critical or aren’t looking to be a core dependency like xz, dual licensing seems the only obvious way forward.
