"There is a growing feeling that Hive is less decentralized..."
It is less decentralized. HF28 increased centralization, again.
"Trying to find the people who are tired of main stream platforms..."
Hive has advertised censorship resistance, and legacy platforms are becoming more censorious. TikTok is collapsing as it's users flee the new ownership and new censorship policies. None of those users is coming to Hive because Hive has long been more censorious that all the mainstream platforms. This is by design, because it centralizes stake, and that is the overriding interest of the oligarchy presently possessing a bare majority of stake that allows it to govern the platform by choosing the witnesses.
The bait and switch regarding censorship became well understood back in 2017, and there is essentially no market that isn't aware of it, so few undertake to onboard Hive.
This is why Hive is not growing, and why Hive will not grow until and unless that governance changes it's policies.
