Using the same line of reasoning, should T-Mobile (Deutsche Telekom) be excluded from the United States? That would be a shame, they have done a lot to shake up the U.S. wireless market. A new entrant in Europe might have a similar effect there.
There isn't meaningful competition anywhere in the USA. Regulatory capture (the famed "revolving door" between the US Federal Government and large corporations) means that major carriers have carved up the USA into territories in which they have a local monopoly. There are other factors, but that's the big one.
While I agree with the premise, the conclusion is too strong. I'm ok with foreign companies running telecoms as long as they are heavily regulated - up to the point of full forfeiture of the infrastructure if they screw with the national interest. Mostly because it is not that easy to define 'foreign' and once you do, it is not clear why 'non-foreign' companies would be less likely to screw the region's sovereignty that 'foreign' ones.
