I know what the first sentence in my link is....you aren't reading it right. This is what that sentence is saying....
A hot wire anemometer measures Air Velocity. A hot wire mass airflow sensor has a theory of operation that is similar to a hot wire anemometer. It's mass not velocity.
Here's more info on the theory of CAI and MAF

Kevin, you are missing some basic properties of physics, hopefully these links will
help you:
First, here is a good explanation for the relationship of air velocity, and cooling of an electronic component. This applies directly to the MAF sensor element:

When a MAF sensor element is coated with a contaminant, or dirt, it will no longer cool properly from the air passing across it, measuring a lower than
actual air flow.
Here is an excerpt from the link below explaining the operation of a Bosch and Hitachi hot wire MAF sensor, which will apply to all hot wire MAF sensors:
