• For Internet Access providers, consider offering, as the default entry level Internet Access Service, something which does not allow external DNS / NTP resolution, to limit some of the methods available to 'malware' that gets on to consumer systems. (mutually beneficial)
Using external DNS servers is an easy way to avoid some kinds of censorship (i.e. that which is implemented in the DNS). What you are really saying here is that users should have to pay more for an uncensored service. Are you seriously advocating this as a best practice? It’s not April 1st yet, I don’t think.
• Customers that have totally free access to the Internet represent additional risk to you, the ISP. For customers that want the full experience, cover your additional risk mitigation costs. (altruistic)
Either I am misunderstanding, or you are using words in a very non-standard way. "willingness to do things that bringadvantages to others, even if it results in disadvantage for yourself" https://dictionary.cambridge.org/dictionary/english/altruism What you seem to be describing is, in fact, the opposite of altruism, "the act of considering the advantage to yourself when making decisions, and deciding to do what is best for you" https://dictionary.cambridge.org/dictionary/english/self-interest Is today upside-down day?
