That's because you're only thinking about your own space/bandwidth
consumption. However, if there are fewer servers, then those ones
will be busier, and download speeds suffer.
On dial-up, you pay for that speed reduction. In fact, when I used
dial-up at home, there were sites (like washington.edu, remember
Pine?) where it was worth telephoning my office machine (on broadband)
to start downloads there, then telephoning an hour later and
transferring the downloaded files (if they were ready) directly from
office to home, with no pausing. This was faster/cheaper than using the
ISP to download those files directly across the Atlantic.
Cheers,
David.
