I'm not sure if this is what aidenn0 was talking about but I think Australia can be considered an example. The Five Eyes seem to be using Australia as some kind of legal testing ground. Not too long ago Australia introduced incredible laws such as legal requirements for companies to serve as state-sponsored malware vectors. Australian companies are now required to compromise the security of their own customers if so ordered by law enforcement. Presumably the other Five Eyes are watching to see how that plays out before attempting similar shenanigans. If it works, I have no doubt they'll use Australia as a shining example to justify implementing the same changes elsewhere.
My own country is an example. The government really likes to copy whatever it is developed countries are doing. Watching how other countries regulate stuff is a great way to predict what I might have to deal with in the future. We created our own GDPR after Europe did it. Telecommunications companies tried to lobby against net neutrality here citing the US as an "industry standard" example.
