Well, it’s more attitude than verbatim licensing, which is the reason the Nextcloud originally tried to partner with them, then immediately changed to Collabora. Some issues:

1. There’s a user limit in the open version. This itself makes it more like a freemium model than open source.
2. Mobile editing and other features continue to be removed.

I’ll just say that while it’s technically FOSS, it’s not community open source. There’s a company that writes it all and open sources a portion of what they write. The company isn’t FOSS friendly and continues to squeeze. It’s not too much different to why MySQL got forked.

I’d count OnlyOffice in that group.

I’m not hosting anything exotic right now, but in the past, before the -arrs existed, back in the 2000s:

• Linux computers in every room, all PXE booted thin clients I crafted myself from a pallete of off-lease computers
• A custom RSS feed to rtorrent to a MythTV setup that migrated video as you walked between rooms.

The first one was actually useful. The second one was more of a novelty I’d show to visitors.

Niche reason: I’m in China and YouTube is blocked. My server has VPN access, but my Kodi system on my TVs doesn’t.

That said, I hadn’t heard of this project, but I’ll probably install it now instead of manually using yt-dlp.
