Because there is no viable alternative. I know of no other competition to YouTube. If I did, I would certainly use it.
Youtube needs to be declared a utility and regulated by an oversight agency.
There are plenty of other search engines out on the web.
I never use Google unless I can't get any results from other search engines. I hate Google, but often their search engine works better than anyone else.
So what are the other video hosting services and why dont we use and promote them?
I would also like to know this. We very badly need competition with Google so we can stop this fascist monster from becoming more powerful. I think the problem is that it would probably take a half a billion dollars to set up something that could effectively compete with YouTube.
The cure would be worse than the disease.
