Well I don't know why it's being done like this, but my informed guess would be:
Resilience. If the content wouldn't be copied, defederating/blocking an instance would mean that the content you created there (topics, comments, etc) would be lost to you. So if you wrote a nice comment, or saved a bunch of topics for later, and then your instance blocks the other instance... that would be gone for you. With the copy this doesn't happen.
Performance. Instead of having to deal with every user (from a different instance) individually, your instance only has to deal with other instances. With this updates between each other can be sent in larger chunks (and definitely with less network connections). Additional benefit: smaller instances don't get knocked down by user-heavy instances when they host a popular community.
Just guesses tho.
All social media is a liability time bomb unfortunately. That's why only the biggest players can afford it so far.
Are the admins of lemmy.world somehow responsible for what their members do, even if it´s not on their own instance?
They are not responsible for what their users do, but for what is saved on their instance. And by any lemmy.world user interacting with content from a different instance, their lemmy.world will host a copy of that content. That's how lemmy works.
So if a lemmy.world user subscribes to a pirate sub, that whole subs content is now mirrored on lemmy.world.
Not just related to piracy that's a huge liability issue for admins.
Those people happily enjoyed the benefits of their society, and now try to get around the contribution part - by spending money they got trough their position in this very society.
Everyone is free to dislike this deal, but then you should find yourself a country which doesn't have a draft. It's as simple as that. But they didn't. They lived in their comfort zone and now try to get around the rules.
Last, this discussion should be about the officials who took the bribes.
I don't think that's entirely fair. Typically answers are getting upvoted when they work for someone. So the top answer worked for more people than the other answers. Now there can be more than one solution to a problem but neither the people who try to answer the question, nor the people who vote on the answers, can possibly know which of them works specifically for you.
ChatGPT will just as well give you a technically correct, but for you wrong, answer. And only after some refinement give the answer you need. Not that different than reading all the answers and picking the one which works for you.
I don't want to compare the behavior, only the quality of the answers. An unintentional error of ChatGPT is still an error, even when it's delivered with a smile. I absolutely agree that the behavior of some SO users is detrimental and pushes people away.
I can also see ChatGPT (or whatever) as a solution to that - both as moderator and as source of solutions. If it knows the solution it can answer immediately (plus reference where it got it from), if it doesn't know the solution it could moderate the human answers (plus learn from them).
Amazing how much hate SO receives here. As knowledge base it's working super good. And yes, a lot of questions have been answered already. And also yes, just like any other online community there's bad apples which you have to live with unfortunately.
Idolizing ChatGPT as a viable replacementis laughable, because it has no knowledge, no understanding, of what it says. It's just repeating what it "learned" and connected. Ask about something new and it will simply lie, which is arguably worse than an unfriendly answer in my opinion.
Yes and no. Yes because the process would work in theory. No because the attestor (supposedly the OS?) wouldn't attest your "headless proxy browser" as legitimate client.
Using a proxy would move the battlefield to how to trick the attestor. But realistically the whole thing will go down this route anyway. It's another arms race. At the very end they'll require cryptographic chips soldered into your device which make sure you're not sideloading any software before running the OS, which would allow you to trick the legitimate attestor of the OS.
They'll introduce Moons, as used in r/CryptoCurrency, site wide. Ticks all the right boxes of a monetization scheme, and the value even appreciates when people are forced to buy Moons.
Sexual harassment is justified because it doesn't affect us personally and people should avoid mob mentality?
So even if you saw sexual harassment you wouldn't step in because it's not affecting you. What a small human being you are.
