All valid points regarding 3Speak.

My biggest issue so far has been uploading times. I uploaded 2 videos, one after the other had finished encoding and it took over 3 days for them both to finish.

But I also support getting people to other platforms.
My favorite alternative to Youtube is LBRY/Odysee because they just seem to have done a great job from the very start.
But I also upload to Dtube, BitChute, Rumble, and I think they are all doing a decent job competing with Youtube.
