Yes @MowTin - a number of people were suckered into buying old GearVR stock and supportive phones with claimed promises that the system was still being supported. I get the feeling that is also true of Oculsu Go's during the current situation!
I have one, my Son bought it me years and years ago. I have a Galaxy Edge 7 running it. I used it a bit, but never bought any software for it, only ever had the free stuff. It's hard to describe, but I always thought the games were over priced and not good enough.
It did go down well at family gatherings though, and that prompted me to get a Quest and Rift S, so I guess in that regard it served its purpose.
For a platform that was released in so many numbers the reality of what the system was is harder to discern. Of the claimed 4m sales, the reality is that the majority of the units were bundled with phone contracts, and were not actually "sold" but off-loaded!
The system also was seen to be locked into a eco-system that proffered high priced VR apps, many of which were less than impressive, and some poorly executed - but still charging full price. The other issue is that the promised feature-set never materialized @Umpa_PC.
The GearVR was victim of the hype regarding VR, trying to pretend it was something significantly more than Google Cardboard, and was also victimized by the breakup between Oculus and Samsung - many trying to down play the influence this had on the business, until the reality of the Oculus Go appearance.
