What would happen if those ISPs notice increased profit and customer satisfaction (overall) when they are paying less for resources used up by bots? (Assuming they don't have problems with false-positives or find far too many customers being cut off, etc.)

I'm an engineer and I don't know even vaguely how much bandwidth is used at my house. I don't count up the uses I know about, but there are plenty of uses I don't know about, like automatic update checks, game usage or at worst, viruses using my bandwidth for their purposes.

People flocked to flat-rate pricing long ago because they wanted access, but didn't want the surprise bill at the end of the month.

Another question: do laws have to be enacted to verify that the bandwidth meter is accurate, the way gas stations pumps must?

Tech vs. Business is too vague a statement really. Many bits of business can't move forward without tech these days, making tech the biggest enabler of business.

I have worked in software development for both internal-only and commercial projects, and saw differences in approach and treatment of the teams. Some of the differences revolve around how money flows.

If your group or project is seen as a "cost center", then someone has a goal of reducing you as goals for costs are always to make them smaller. (By "cost center" I mean that money is spent with no possibility of revenue. Money is spent to keep things working which were already paid for.) For these projects, being able to say something like "we saved the company X tons of money this year" was good.

If your group/project is seen as a "revenue center" then there is as least a possibility that some product of yours will be used to make money somehow. These projects have pressures of their own, but I was always surprised how much easier it is to justify resources for them. Here the sales staff is almost always on your side.
