• no ads or sponsor crap (sponsor only if sponsor is <5s and only at the start of vid)
• buffering is efficient and quick
• subtitles available in widescreen, small etc
• can change volume and resolution
• can be judged by community with a non-karma system
• little to no algorithm or AI slop
• can custom select videos (by date, popularity, tags, or whatever)
• peer to peer, decentralised and FOSS
• privacy friendly
• can download, usable offline
• none of that copyright bullshit

In short, a no-nonsense normal video player without a profit motive.
