In this connection, I once came across a user
who had written some Stata ados and was selling
copies of them. I regret that I have never met this
person or otherwise found out how many purchasers
there were. As far as I can see, there could be no
real objection to this if it was all original work,
but it didn't ever catch on as a way of interacting
with other users.
