1 Haza Autonomy?
It is on Smashing Magazine, so aimed at web developers. For hosted IndieWeb services, I noticed that Malcolm has added a way to use Haza.Website without needing to register a domain straight away - https://no.haza.website/.
2 The Social Dilemma
I don't know much about CHT. I listened to a few episodes from Your Undivided Attention a while back and they were very interesting, though I have a vague memory of thinking they seemed to skirt around to avoid the C word (capitalism).

Diversity is absolutely a problem in tech, but IndieWeb folks are, from my experience, absolutely doing what they can to rectify that; bringing in people from all sorts of backgrounds, trying to boost the minority voices, and being supportive of everyone who is trying to make the world, or at least the Internet, a better place.
This is a really good article by Fluffy on the state of the IndieWeb and making it more accessible for wider adoption. Just because we're not there yet, doesn't mean that we're not trying.
Related: this is a really fun listen from Doug Belshaw. He discusses IndieWeb and the issues he sees with it.
Doug has a preference for the Fediverse as an approach to an open web, and says the political philosophy of the IndieWeb is a type of right-libertarianism, because it lacks social equality, and without that it is just a focus on individual freedom.
My gut response is that I disagree of course. But it's a great jumping off point for some thought and reflection…
