Yep, exactly! I live in Switzerland. The article is misleading. Switzerland doesn't have 25 Gbit consumer internet, quite obviously, as nowhere does. It has a state-owned telco that advertises 10 Gbit to ordinary consumers without making it obvious to the buyer that they won't be able to use anything above 1Gbit without exotic and expensive equipment they are near-guaranteed to not have (unless they're literally a high speed networking hobbyist).
I noticed this years ago and thought it was an extremely sharp and therefore unSwiss practice, that in a more free market with better regulation and a more feral press would have already attracted a rap on the knuckles from the truth-in-advertising people. But Swisscom is government owned and has fingers in a thousand pies, so they're allowed to get away with it.
Unfortunately because regular consumers just compare numbers and assume higher is always better, this practice has dragged fully private ISPs into offering it now too. So the entire market is just engaged in systemic consumer fraud by this point. God knows how many people are overpaying for bandwidth their machines literally can't use without realizing it.
That said, the basic point Schüller is making is sound that the fiber cables themselves are more like roads than internet. They aren't a natural monopoly but the cost of overbuild is so high that it makes sense to treat it like one. It's just a pity that in the end this doesn't make a difference as big as the article seems to be advertising in its title.
