Why should they? There is a resolution to this, but some people don’t want to take action that will solve their own problem. Instead they want others to do it for them.
When I had dial-up, I had to make the setting I just mentioned. It’s not that big a deal.
Please, give it a rest.
I'm on rate-restricted dial-up, and to go full-rate dialup would cost me a second phone line or maybe a fleet-up to ISDN at a minimum; and broadband would also be more expensive. We all have budgets to manage and means to budget.
