Massport says it wants to avoid interference from a bunch of competing wireless signals, but the airlines (including American Airlines) argue that what it really wants is a monopoly on Wi-Fi, for which it charges $8 an hour. I’m with Fred Wilson (and others) on this: Wi-Fi should be a form of public infrastructure, like roads or bridges.
I also like an analogy I first saw in a Wired article by Paul Boutin: Wi-Fi is a condiment, like sugar or cream, or salt and pepper. Providing it is a service that you hope will make people want to come back to your establishment. Hardly anyone charges for the use of their washrooms either — not even airports.
