Encryption is an exemplar. It applies to all features in XEPs. My comment fully addresses two of your three dot points so the claim that I only read a fragment of a sentence is bizarre and patronising.
I don't feel the need to address every point because I'm not setting up an opposing argument, I don't even disagree with the overarching concept. I wanted to clarify some aspects of XMPP that I see as being misrepresented or overlooked.
I don't think it's reasonable to say XMPP both lacks encryption and has a XEP for encryption. XEPs are how features are added to XMPP. There is support for encryption in the XMPP standard because there's a XEP for it.
The feature fragmentation used to be a real problem, which is why they introduced compliance suites.
Content creators. It's hard to host everyone's videos, and it benefits monopolists to imply that doing so is necessary, as it prevents new entrants. It's not nearly as hard to host your own server (or pay for it to be hosted). It becomes harder when you suddenly become popular, a situation which Peertube explicitly compensates for by sharing the distribution effort between viewers, which scales with popularity.
Signal makes it's own bed like YouTube by being a single centralised server for everyone. Nobody ever asks "who pays for the servers" when it comes to Matrix or XMPP
Peertube has already delivered the sustainable model: creators host their own videos and viewers assist distribution.
You wouldn't happen to have any resources regarding how to run a community makerspace, would you?
... did they stop putting PSUs at the top?
Monty Hall Problem, for those who know that name
Honestly I think this is a gap in the community.
They're more project focussed but you could consider https://hackster.io/ or https://hackaday.io/.
Maybe consider cross posting this question to an open hardware community? Such as !libre_hardware@lemmy.ml
(And ping me if you find one, I'm collecting open hardware websites)
If you find an answer to that please let me know
Just to be clear before I respond to the rest of this comment, my position is that Peertube solves the sustainability problem and in no way am I suggesting Peertube will replace YouTube
I do not expect the vast majority of channels to survive the end of YouTube, as is normal for any paradigm shift.
P2P is completely achievable using NAT Hole Punching. I have no clarity on if Peertube is doing this but since there's already a trusted server involved it would be silly not to.
In a hypothetical, unlikely future where YouTube dies and people generally move to Peertube, I expect the majority of content creators to pay small fees to have instances host their videos. I expect small, free but restricted instances will continue to be the home for amateur videographers as they are today. The more technical folk will likely self host, and groups of like minded creators will pool efforts to run group specialist instances (not unlike Nebula).
Frankly the most likely scenario is YouTube dies and everyone starts posting videos to Instagram or Tiktok or something equivalently anti user.
