All the majort powers in the world spy on each other.
They know that they each spy on each other. Friendly nations spy on each other; foes spy on each other. If nations know they spy on each others' 'national secrets' and don't publicly do much about it, I don't think they'll care much about the more quotidian things each other might record about their masses of people. Would the US care that France recorded American civilian citizens comms? I don't think so. Same for France. They might make some public fuss about it, but they care more about the spying on 'sensitive' information --and even then it's more of a 'game'.
