Paid support is the perfect way to support the open source development of wordpress. Corporations that use wordpress depend on it to work and require more than the free helping hand offered by the community. They need guaranteed response times to fix problems immediately, which is something they must pay for, so why not automaticc, the ones who actually make the software? Pretty sensible if not great idea.

Most individuals and smaller companies will not pay for support, and so the open source community will remain as thriving as ever.
