It is often claimed that only a few developers moved from TWiki to Foswiki, therefore the first article will look at who are/were active core developers of both projects.
Number of core developers
The analysis focus on core development of both projects, as this is a major indicator for the health of a software project. This is because you need a lot more knowledge and background for developing the core product than for writing an extension with a clearly defined API.
Claim
"We have healthy downloads, an active user community, and a very active support community. However, we are a smaller developer community than we used to be."

Statement
Developer community:
Look at the list of developers contributed to the core of both projects since the commercial takeover of Twiki.net. The TWiki.org development community has dropped to almost nothing – only Peter and his employee Sopan is left. Whereby all other TWiki.org core developers moved to Foswiki.org. Together with new developers, Foswiki has almost doubled its core contributors!

Healthy Downloads:
Yes, lots of users still download the old TWiki code as they don´t know about Foswiki and its progress. Our marketing was very bad as we are better in concentrating on improvements than in talk about it. Sadly even most of our old TWiki user community don´t know about Foswiki and may wonder why there is no progress on TWiki.org.

As the analysis is based on open source, you can easily check the correctness of the data by yourself. For the first analyzation I used the following sources:
Sven Dowideit made a reasonable comment on IRC as well, with links to some objective sources that confirm your analysis:
