This is rather inconvenient when shopping for niche products. American website assumes that everyone on the internet is American, and you have to go through the shopping cart experience to learn that they don't ship to Canada or Europe.
TBF internationalisation is complicated and hard to do well. So is international shipping.
But compare with a European site like thomann.de, which not only handles currencies and taxes but also (mostly) translates the product descriptions into most European languages.
They forget that in the telecom-backwater of Canada, a 4 or 5gb/month plan is near the high end.
I’m looking at you NPR One app for thinking buffering 300-400mb of content is a good idea.
The thread seems overly negative towards Americans and criticizes them heavily because half of America is still asleep and the other half just started working. If OP posted it later Americans would likely be filling the discussion with the reasons why your complaints are happening.
My personal opinion is that US-centrism is obviously a thing, but EU people are so used to seeing it that they then mistake other things for it.
This same thing happens with Spain and Mexico as well!
I'm not talking about currencies. I'm talking about sentences like "if you move to the east, you'll earn...", "in the south, it's..." in conversations with no prior indication that it's just about US and "the east" means "the east of US" and "the south" means "the south of US". Because US is the whole world and there is no need to clarify...
Meanwhile, you'd struggle to find an American, or any one from the Anglosphere really (maybe with the exception of Canada) who speaks Greek, French, Arabic, Vietnamese, etc.
