My first internet connection was through a 28.8k modem, I know very well that it wasn't flat at the time, and that's exactly why I said that "pay per minute of use" is terrible for consumers compared to today's situation, while the OP said: "...as it had some aspects which were (and still are) significant downgrades.
Monetisation is a big one, Minitel had use-time payment very early on"
I'd say the Internet still doesn't have a very good monetisation system. Card payment is several times too much effort to use, takes a good couple of minutes, and isn't reasonable for a one-off service. PayPal and similar services are a mess, and not much better. The point wasn't that use-time is good, it's that there was monetisation integrated into the design of the system, and it was easy for the customer to use.
