probably because of the lighthouse tracking / licensing
Well, it just says “Developer” ?
It might be related to the VR consortium. Though asking the team would possubly yield the best results.
Lighthouse has nothing to do with HTC, I agree with Heliosurge
This was on the “vive wave” website. Above the picture it says “partners”.
Strange, for me it only shows qualcomm and unity as partners under VIVE Wave | HTC VIVE
Even in your picture there seems to be a white divider above the “brands” 
They are a partner listed here:
Today, at our Vive Developers Conference (VDC) in Beijing, we announced the VIVE WAVE VR Open Platform. With it, we are taking another huge step in driving the most vibrant ecosystem for VR forward. Vive Wave will open up the path to easy mobile VR content development and device optimization for third-party partners. So far, twelve hardware partners in China, including 360QIKU, Baofengmojing, Coocaa, EmdoorVR, Idealens, iQIYI, Juhaokan, Nubia, Pico, Pimax, Quanta and Thundercomm, announced their support for Vive Wave and integrating the VIVEPORT™ VR content platform into their future products.
@jonnypanic mentioned awhile back that Vive Port/Wave was an easier platform to launch games from.
Maybe partner about All-in-one module to install the software from vive store.
I don’t think the two are related. Viveport is just a frontend, like Oculus Home.
