I’ve been moving off google services to privately hosted email. Apple seems to care about user privacy more than other tech companies. There’s nothing wrong with ordering online, without internet services our lives would be worse and I wouldn’t have a job. I try to order from small businesses over Amazon whenever possible.
You can reduce your dependence on big tech without eliminating it entirely. The world isn’t black and white. Facebook in particular is far more offensive to me than any of the companies you named, so I expend extra effort to avoid it.
For years I’ve thought the hardware is the problem. The experience of all past headsets —- since the Oculus DK1 —- has been good enough to get a feel, or idea, of what this could be, but has never crossed that line where VR can become mass market. Discomfort, simulator sickness, and that “cross-eyed” feeling are something enthusiasts can push through, but the masses still view VR as a tech demo. And until there is a mass market install base, no-one is willing to spend the money creating great content.
IMHO this chicken-and-egg problem will only be solved when there is a step change in the hardware. I hope the Quest 2 is it.
