The issue is that a dynamic site that can serve the traffic that generates 10MB of logs a week might be very performant on the smallest and cheapest of virtual servers, but one that generated a GB daily might find itself very slow and sometimes crashing because of load depending on spikes, unless they opt for a server with more resources, for more money.
Any answer to that along the lines of "do something more complex" or "optimize your site for load" to be able to deal with the rampant bad behavior of multi-billion dollar companies is unpalatable to most.
