Why isn TexPoint free?
TexPoint was free from 2000 to early 2006. In that time I have received many bug reports and requests for features, but only one person actually contributed bug fixes. I think this is because the user base for TexPoint consists of people who have little interest in digging through the internals of Powerpoint and Windows. In March 2006 we have decided that we can either let TexPoint become stale, or we can add a financial incentive to the equation. Furthermore, we thought that most of our users are professionals who could charge the cost of licenses to their institutions. TexPoint is not free anymore, although it is quite cheap and you can do a lot with the features that do not expire in the free version.
