Pharo continues with a not invented here policy, and has made no attempt to review the code based for projects that could be mutually maintained.
I think it is a misanalysis to label that NIH, there are quite different factors contributing to the lack of pushing contributions upstream.
This is a problem, and I shall continue to point it out until it is resolved. It's a mindset issue.
As it happens your timing is unfortunate in that a discussion was just kindled here on which processes and mechanisms to put in place to solve this issue. Unfortunately a lot of messages have been posted here to the effect of making statements without proposing solutions, washing out the original constructive thread.
This is not a fighting attitude, its a pragmatic attitude aiming to help people to avoid wasting their time and effort.
It would help if the balance of the message traffic moved from pointing out problems towards discussing solutions. R -
