I certainly agree that UW should expand it's CS program even more. FWIW, they are doing it but probably not quickly enough:

I'd have to disagree on the "slight discount" argument. UW charges $12,000 per year for residents. This is 3.2x cheaper than non-resident tuition ($39,000). IMO $12,000 is still a very good value for what you get.
