England is fine because the AI rarely prioritizes me(unless I'm her only neighbor) since I'm not the highest priority for them to focus when I play on Deity. So if you're suddenly snowballing and this English spy is on your doorstep pickpocketing your gold and sabotaging production...
It's just a huge observation bias from the complaints. Try AI-Playtesting with England in the game and they'll relocate their spy to whoever is the highest threat and if that's the player then it's the player.
Then you try giving one AI that England knows a big wonder-production bonus and you'll be sure England will never relocate their Spy until much later or that AI's threat is significantly reduced.
Besides if I was the AI and I had to plant my only spy, it'd probably be my highest priority target who might be the player if he's playing on a lower difficulty.
