well, doesn’t it make sense when the business-model is to recoup R&D cost of the console with expensive games?
DRM becomes much harder once you can’t trust the system anymore.

Nintendo tried to lock the system down, and got fucked by NVIDIA.

nextcloud talk can also be an alternative (open source and self-hosted).

but I think the whole nextcloud suite is more suited as a hub for a (small?) business, not necessarily great for, lets say, family videocalls (due to the necessity of having an administrator who runs it).

I think it may be decent, but the homepage is not convincing me.

I had a tiny little look, and don’t like that I had to log in (although selfhosting seems to be possible since very recently), and then had a weirdly full notebook. It also seems like they don’t save their data in nice little markdown files, but use some custom database-stuff.
They probably allow exporting into markdown, but I’d prefer it to be stored in a legible format.

Overall, I had a look, and I’ll stay with logseq + syncthing
