Lemmy, piefed, and mbin are all similar pieces of software that run on a server.
They are each capable of hosting a small social network website with a similar reddit-like format. They all also support the activitypub standard, which means that they can be linked together, so that when you go to one of those social media sites (lemmy.world for example) you can see any other site that they're "federated" with, even if that social media site is powered by a different software that supports activitypub (I'm on lemmy.world but I can see communities and posts from piefed.social)
I generally call lemmy, mbin and piefed "fediverse platforms" because they're each a platform that you can make a fediverse account on, but that usage is a bit imperfect, since each individual site could also be described as a platform, and is where your account is actually hosted. You could be more specific and call them "fediverse/federated link aggregators" if you wanted to specifically refer to the ones with a similar format to reddit.
These pieces of software are different because they're built in different ways (different languages and underlying structure), have different priorities, and as software projects are run in different ways with different leadership, all of which is how you get differences in features and implementation. Lemmy is the oldest of these similar platforms, and as such is the most established. In the open source world it's very easy and common to end up with a lot of fragmented similar projects. Its both a blessing and a curse.
There isn't perfect language for all these things because in the grand scheme of things, it's a rather new way for social media platforms to work, so the language around how to describe or refer to these things hasn't really "settled"
It can federate with lemmy, essentially just being another type of node in the same web of individual websites.
Some of those sites are hosted with lemmy, some are hosted with piefed, some are hosted with mbin.
Each of those (lemmy, piefed, mbin) is a piece of software that can run as a "server" for a social media site, and can use the activitypub protocol to talk to other sites that are federated together making the contents of other sites visible. They can federate regardless of whether the software powering the site is the same or not.
I'm not really convinced many IDF soldiers are facing significant risk of losing their life, at least in combat- my impression has been that they and Hamas aren't exactly evenly matched in terms of resources 😅
I could absolutely be wrong, I'm not terribly well informed on the conflict and what combat casualties each side has suffered
Massive respect to iraeli soldiers willing to defy their country. For many (certainly not all) criticising the war and senseless loss of life is an easy thing to just throw out on social media. It's another thing entirely when it's your whole country around you, and you're a member of the military. There's a reason we see people comit atrocities while "just following orders"- it's by far the easier path when you're handed down horrific orders.
I cannot imagine the consequences they might face for this kind of insubordination but it deserves recognition. The killing serves no meaningful purpose.
I believe the part they consider performative is just the expectation that people who already have them need to get rid of them, sustaining a really big personal loss with no direct benefit in terms of hurting teslas bottom line. But I can see how their exact phrasing could be ambiguous what they really mean
Ah, it's ios, but it looks like a lovely lemmy client! Have fun with the update 😊
