Apparently even his lawyers, from TFA:

"It was Julian Assange who suggested holding the legal meetings inside the women's toilet due to his suspicion of being under intense surveillance. Lawyers had considered it paranoid on Assange's part, and UC Global had reassured them on this count, but in reality microphones had even been placed inside the women's toilet."

If so someone should easily be able to provide a few links to historical comments saying that.

You would have been attacked and called a conspiracy theorist, putin troll, chinese bot, among other things by journalists, think tank workers and depending on the time - by republican supporters and democrat supporters.

Governments spy on a wide range of people, it would be illogical to call someone a conspiracy theorist for asserting that the US was spying on Assange and lends doubt to your claim that most would be rebuked as such based on that alone.

In contrast, evidence that the US Intelligence agencies actually framed Assange for rape would be much more newsworthy.
