They do offer a free API but it is nowhere near as full-featured as WU.

While I don't disagree with you that the NWS has thousands fewer weather stations than WU, it should be noted that the NWS has very strict standards for weather sampling and reporting.

NWS weather stations are set up in a particular way to ensure consistent, accurate data. WU, less so.

For example, last week I was in a part of the country where the only weather station for 80 miles was a PWS from WU. According to its data, there is a 40-degree (F) spike in temperature every morning around 7am. Clearly, this is a thermometer that is being affected by the sunrise. This doesn't happen to NWS equipment.
