So you're speaking of a specific problem in a specific place - this is kind of hard to know when it was phrased as a general principle. Also, it's hard to discuss the issue when there are no details about the specific issue available. But two points: First, where I am, 2.4Ghz is perfectly swamped with normal residential access points. It seems unlikely that this telco in your city did much more than move up the point where the spectrum is swamped, rather than causing it directly (also, if their use is affecting everyone else, they themselves are affected, too, rendering their investment pretty pointless, which leads me to wonder just how bad the situation actually is). Second, if you do want to regulate, in a rule-of-law-compatible way, well, it's going to be hard to distinguish a Starbucks access point operated for the benefit of customers of Starbucks from a telco access point operated for the benefit of customers of that telco. (If you want to use spectrum ownership as the metric, consider that many telcos cover both spectrum-owning mobile and commercial and residential broadband (ie wifi-providing) subsidiaries). To further muddy the waters, the telco is very likely to be selling access to their wifi network to non-subscribers.
