Cascadia: environmental movement or anti-Microsoft plot?

This picture is of the flag of a proposed nation in North America known as Cascadia. According to Wikipedia, the concept of this nation, consisting of the American states of Washington and Oregon and the Canadian province of British Columbia, is closely identified with the environmental movement. But think about it: is this really so?

Here's my theory of what's going on: Seattle alone is home to several companies like Microsoft and Starbucks. However, Apple is headquartered in Cupertino, which is in California. This means that Apple fans can discredit Microsoft by attempting to kick Washington State out of the Union. Once Windows users learn that Microsoft is no longer American, but Cascadian, then the most patriotic of them would lose faith in the Windows family of operating systems and get Macs when the computers they're using now are no longer useful.
