are competing for market share, and anything that will attract customers is fair game in the battle for the available revenue streams.
Supplying Internet access is a tricky business - the margin between success and failure is narrow to say the least - and in this phase of the internet's development only the fittest will survive. In this context 'fittest' is likely to mean 'biggest', and that's why the likes of BT and Tiscali and AOL have their horns firmly locked in battle.
"All this is good for consumers" I hear you say, and you're right up to a point. My own view is that for the future we need efficient, go-ahead service providers with enough money to invest in emerging access technologies. If competition is so aggressive that nobody can make any real profit we're all on a fast train to nowhere.
