The end result of this strategy seems like “invest in Steve Jobs, Elon Musk, Mark Z and Bill Gates”. Doesn’t sound very contrarian.
Hint: The contrarian here is not the thousands of people/institutions/funds buying on the float.
By your definition owning an iPhone is contrarian, because there are only 1billion people with iPhones.
To use your example, I would consider choosing to not use a smartphone to be a contrarian position while having an iPhone is not.
Also, not to nitpick, but Jobs and Gates are no longer running their companies, and Zuck is down to part-time. I don't consider either of those companies at the same level of growth potential as Apple back when Steve was running it.
