What’s really changed 10 years after the Snowden revelations?

The whistleblower forced US intelligence agencies to admit extensive spying on their own citizens. Some reforms were enacted but Snowden still faces potentially 30 years in prison

It was the day his life changed forever. When Edward Snowden blew the whistle on mass surveillance by the US government, he traded a comfortable existence in Hawaii, the paradise of the Pacific, for indefinite exile in Russia, now a pariah in much of the world.

But 10 years after Snowden was identified as the source of the biggest National Security Agency (NSA) leak in history, it is less clear whether America underwent a similarly profound transformation in its attitude to safeguarding individual privacy. Was his act of self-sacrifice worth it - did he make a difference?
