Is that they rely on IT Teams to deploy their collaboration tools. IT Teams perform an analysis and lock down everything that they can before rolling out the product.
The locked down collaboration tool is unable to be used for collaboration and everyone finds some other way to get their jobs done.
The last two companies I have worked for rolled out SharePoint in such a way that people quickly learned to not allow their documents to become captives in the "collaboration tool" and the ballyhooed sites became unused. If Microsoft does not plan on providing a free/consumer offering then this tool will be relegated to the same dust heap that most SharePoint servers have found themselves in and for the same reason: the people in control are not the users.
Stolen -- incorrect and inflammatory verb use.
Unattributed -- The repo is named "wix/WordPress-Editor-Android"
Wix seems to be in compliance with the GPL. The source for the entire version of their editor is available on GitHub. Matt Mullenweg seems to be aware of this repo and yet he insists that there is some additional and unidentified code that is not publicly available. When one uses terms like "stolen", it is irresponsible to not be explicit about the details.
Things equal to nothing else are equal to each other.
