@aidan_walsh yes, same with Nextcloud and Pydio. All projects are split up, as I note in the blog, which is why I also looked at statistics from OpenHub which looks at ALL repositories associated to a project.
However, in a conversation with Seafile, it came up that their specific way of organization and way of working does make them look worse than it is: while github also shows lines of code changed, OpenHub does not. And they say their core contributors work often with very large commits so it doesn't show the activity very well relative to other projects. It still shows a decline in activity the last year or so, though, but they said the fork had no effect as the German team didn't contribute code anyway.
Note that I wasn't out to specifically make anyone look bad, though obviously putting the numbers next to each other makes clear how things are, relatively speaking. That is why I sampled a wide range of numbers rather than cherry picking the last day or only one statistic.
Alas, it is still statistics, and you can only trust those you doctor yourself, so all the links in the article go directly to where I took the data from and people can check for themselves.
I honestly didn't know what I could do in a nicer and more balanced way to point out how we're doing and how that stacks up in the open source file sync and share world. But suggestions welcome.
