$60/yr for a touchpad driver for every Linux user in the world is quite reasonable. Plus, you get to stop paying after it's done, and no one can take it away from you :)
I sponsor this project for $5/month. Started a few months ago. I'm happy to support! For Linux desktop to succeed with consumers like me, it has to move beyond being for mechanics only, which means we have to do our part and pay money for it.
