Here's an easy way: promote the use of a security cryptographic communications protocol. Fund development of a plugin for Windows. Advocate or even pass a law that banks, the IRS, and other organizations support it. Ignore requests that the code be published and/or available for other OSes. Ta-da! You've effectively discouraged use of free OSes.

Okay, it's still possible to have a system without proprietary software. Just much harder, and not worth the frustration to most people.

See the links from http://en.wikipedia.org/wiki/SEED as an example of that scenario in action in South Korea.

It would be reverse engineered pretty quickly.

Reverse engineering code is pretty hard - but that sounds like a lot of motivation.

Did you read the link? "Unfortunately support for SEED alone is not enough to allow for secure transactions with Korean web services."

There's motivation, but still something missing.

What's missing? The wiki page doesn't say.

Strange! I go to "http://en.wikipedia.org/wiki/SEED, I search for "not enough" and it's on the end of the first paragraph.
