That he went to MI6 because the Russian government was targeting him? Because he had information about it's operations that he felt was not good? Who do you want him to go to, the CIA? What are you talking about?

When Snowden came out about the NSA, he went to Russia. Not because he's suddenly a Russian agent and everything he says is a lie, but because the United States was after him and alongside Russia he would find safety from them. Flip the script, same situation. You're literally asking for the only source to be Pro-Russian which is a fuckin laugh you clown.
