Ah, because most of them aren't licensed amateur radio stations legally authorized to transmit their weather data on the radio? :-)
aprs.fi has data feeds from more than just the APRS-IS backbone. There is a separate backbone (using APRS-IS protocols) called cwop.aprs2.net which carries just unlicensed CWOP traffic, so it can't get accidentally transmitted to RF (and put the Tx I-gate station owner at legal risk). There is also the FireNet, which carries traffic from non-amateur-radio sensors of interest to fire, emergency management, and weather services.
If you would like to see the CWOP traffic in your YAAC client, open an APRS-IS port in YAAC pointed at cwop.aprs2.net. Make sure this is a read-only port, and that you are _not_ configured to forcibly Tx-I-gate the weather traffic through any RF ports you have. Note that you can have more than one APRS-IS port open in YAAC, so you can be connected to amateur radio APRS-IS, CWOP, and FireNet simultaneously. However, you should only transmit to the regular APRS-IS network (and that only if you are licensed youself).
Hope this helps.
