Ireland is a western country, just not very anglophone (though it is more so than most other Europen countries, for example).
Like others have pointed out, if you read and write in English on the Internet, you're most likely visiting anglophone platforms, thus it is natural to never get to know, let's say, the Portuguese Internet "culture", with all its popular websites and quirks. I'd say every country/language has something like this, with varying degrees of richness and popularity of course.
It is true, however, that the USA's influence on the western Internet "space" is way more significant than any other country's, which can be attributed to a myriad of reasons, like how they had a big role in its inception and how their economy has evolved to flourish the tech industry.
