None? I don't debate that Blue Sky is corporate-owned while Bitcoin and the Fediverse aren't. Rather, I'm saying the thing they all have in common is that they like to think of themselves as "decentralized" federations of independent systems and users, but in reality they are all "centralized" systems with shared weaknesses. This is the "ideological contradiction" I thought you were referring to.
Put simply, yeah. lemm.ee can communicate with lemmy.world, and kbin.social, and mastodon.social, as they're all "federated" with each other (like a federation of nation-states).
In the future you might see bsky.social and bsky.io and bsky.jp etc etc, and they'll be able to talk amongst themselves, but they won't be able to talk Lemmy or kbin or Mastodon.
This is the same criticism that was made of cryptocurrency's claim to fame regarding decentralization, consensus, and resilience to authoritarian takeover.
"If you take all these different parts of your identity, all the games you play, all the things you buy, all the groups you join, and stick them into one system, that's a central system. It doesn't matter how many servers that system spans, you've pooled all that data in one place."
And ultimately we can make the same criticism of the Fediverse itself. It's nice that there are different platforms, different instances, different communities... but it's still just one entity at the end of the day. This is especially apparent with the spam wave we just saw. Misskey, Mastodon, Lemmy, even kbin was not invulnerable. You don't need to attack them individually, you can attack them all at once, and then they will naturally spread your attack to other instances for you.
I'm hardly a Sony Stan, but you can call me one if it makes you feel better when I say... I have no idea what you're talking about.
hardware component shortages that were notably specific
What was specific to the PS5 that wasn't shared by the XSX? The specs of are almost identical. Same AMD processor, same generation and architecture, same amount and type of memory. Any supply chain woes that affected one almost certainly affected the other.
It is well documented that the PS3's weakness was the complexity of it's design not necessarily how powerful it was.
the PS5 enabled and enriched scalpers
This is such a confusing statement, it's Not Even Wrong. You make it sound like Sony built scalpability into the PS5. You're angry at the inanimate object? Not what the awful people did with it? People scalped the PS5 because it was in higher demand, not because it was made of gold.
