BTW, who would use FB to watch videos? It is a joke to compare FB to YouTube which has millions on videos with content on virtually every subject matter.
Who actually likes the FB interface? I think it's the most clumsy web site ever - there's nothing intuitive about it.
Why use FB for messaging?
And who likes being bombarded with ads and more ads. FB doesn't care about improving their web site, only about attracting more advertisers.
