>How HN can support monopolization of markets and killing of [sic] competition is beyond me.
That suggests HN is a monoculture of some sort of united front. It is not. Diversity of opinion is best for this community (and all communities).
And, sorry, what competition was killed off here? I, as the consumer, was never considering Massimo for my blood oxygen measurement needs. I bought an Apple Watch and just want it to be as feature-full as possible. So does Apple.
