They do, they just care less when it's friends doing it. 5-eyes did the same with the entire European parliament. The incident response & reporting ( clean up crew ) was done by a firm who got sold to a British intelligence daughter not much afterwards. You can't make this shit up.
Another famous example would be from the previous cold war era. Dutch telephony routers had Hebrew manuals so they required personnel from Israel for "maintenance". They wiretapped the whole country.
