Re:fediverse - it depends on which communities you're part of. Digital rights, politics here in Canada (see e.g. https://mstdn.ca/@avilewis), politics in the EU (https://ec.social-network.europa.eu/about), basically anything that touches Linux is very much entrenched on the protocol. My local newspaper (https://thetyee.ca/) has a Mastodon share button on the page even. Unlike with Bluesky, leadership has been very consistent and so far trustworthy.

Which fediverse leaders do you mean?
