Say what?
Many of those things are just tracking pixels. There is no way to serve them from the site host, that's the whole point. And if they fail to load, nbd.
And sure, if some substantial piece of JS or CSS doesn't load, that could cause problems on the page, but in most cases it wouldn't cause total failure of the site loading.
Public CDNs for shared assets makes a lot of sense.
These things are nothing like hotlinking somebodies image.
CDNs are supposed to decrease load times but in my experience it is the opposite... sometimes I wonder if CDNs exist only for data collection purposes.
