Say that to my Google Cardboard SDK programs, or the Google VR SDK ones, or Google Daydream ones.
You couldn't have chosen a worse topic on which to dump a generic "ranting about Google abandoning projects is low effort cheap shot", because Google does abandon VR projects (including OSes and APIs, not just devices) every 5 years, almost like clockwork. What I would call "a cheap shot" is to think that this new fancy "OS" will be any different. In fact, I pity the people who still consider jumping on this particular bus _again_.
