> Traffic doesn't cost money.
Mostly false. Either transit is billed on a 95th%ile basis (so...more money for more traffic), or if it is flat/netted, you're still paying for the capex for the switch ports (fatter connection to support more traffic means more $$$ for the gear to support it).
What switch port costs $105,000 a month?
At Netlify scale, it'll be the latter. And the appropriate thing to do with free-tier traffic is set lower QoS so it doesn't interfere with paid traffic. This, it doesn't have cost.
You can say "the sum total of free-tier traffic requires X additional connections" but the sudden burst of DoS traffic did not raise marginal costs (besides an inconsequential usage of electricity).
