1. Yes, it is true that more nodes equals more people being able to use it.
That is obvious.
2. What you are describing as legitimate is very subjective. I do understand
that people need an outlet sometimes to discuss information, but like I said
a handful of times, the owner of the IP becomes liable. If someone provides
an exit node for someone to use it for illegal purposes, doesn't that make
them an accomplice?
3. I don't use Tor every day and using it to stream a video from the BBC only
really happens if I want to see something in the iPlayer. If you are
chastizing me for that, you are really being hypocritical. You say that Tor
allows people the freedom to access and process information regardless of the
country they are in and for a person in the US to access services on UK
servers is no different than someone in Japan trying to access services on US
servers.
No matter what, Tor allows someone access to something they are typically
denied to by the rules of their country. If accessing Google is a big thing
for a Chinese user, many times than not the Google servers will detect that
the IP is under a type of proxy and will not let you proceeed. Of course
someone can get around that by using DuckDuckGo or Startpage from the start
regardless of their country.
