Having played Halo CE for PC recently…no, it doesn’t have split screen at all. That was only on the Xbox version (which is technically superior in quite a few ways). The only way to have split screen on Halo CE on PC is via console commands/mods. That said, I do agree with your overall point and I would love to be able to do split screen MCC on my PC without mods.
It’s the cost of federation with instances that try to be giant general-purpose instances (.world and .ee, mostly): just constant shitty takes that overwhelm participants in the conversation. Federation works far better with lots of small purpose-driven instances instead of gigantic ones; my small (<1000 users) specific community-focused Mastodon instance sees absolutely nothing like this and is full of people who intentionally engage in good-faith conversation with the rest of the community while every large instance I’ve seen has the same issues as centralized social media in that regard.
Is there another alternative? Bandcamp is the only similar website that a lot of artists I enjoy use.
This guy has been spamming garbage everywhere. sh.itjust.works is a terrible instance with no moderation and this quality of post is pretty normal from users there. I don’t know why they haven’t been defederated en masse when other less spammy/disruptive instances that actually contribute to discussions have been.
