The fact that it is based in the United Kingdom is concerning given the UK's government seeming wanton zeal for censoring people (I'd include the despicable treatment visited upon Tommy Robinson among some of the other issues you've already identified).
BitChute is actually a peer-to-peer platform, it is based on WebTorrent.
I do support projects that are less centralized that BitChute, such as DTube, but I don't know of another platform that has enjoyed adoption by creators more than BitChute, which, while unfortunate, is key to functioning as a proper surrogate to YouTube.
Ultimately, with the censorship issue, it seems unlikely a truly decentralized platform is possible with today's internet infrastructure. Someone has to register a domain and host the website's code, which is always going to introduce a degree of centralization even in blockchain based projects.
