While potentially true, I don't see how posting on HN is protecting much. What's more likely are ofc people who work in relevant spaces who are paid to maintain the walled gardens who therefore are incentivized to not accept criticism of said systems.

If you think about HN, it seems a good deal of the (annoyingly :) pro Apple users are just ordinary happy Apple users, not astroturfers.
