Steps in the Right Direction:

IPFS is at least a step in the right direction, it is like Bit Torrent, and I believe Bitchute uses something like that. Anything P2P is key. My question to developers would be in regards to how we might store video, photos, memes, files, etc, on blockchains, cryptocurrencies... I've heard people talk about attempting to store video on Bitcoin in a way but more like part by part or bit by bit.

Super Mega Computers

I wonder if quantum computers could help. Well, I take that back as those type of computers can be big and expensive. But I do like to theorize ways for storing video on blockchain without putting too much pressure on blockchain as video files are generally larger than text files. I guess if everybody suddenly had super mega computers, then we all could somehow afford to have bulky blockchains with videos encrypted or whatever.

Honest

And yeah, you're right that 3speak and others should simply let people know like you said that they are probably not decentralized either at all or not in regards to the actual video files themselves.
