30 is a bit of an exaggeration don't you think? I counted 13 tools, 9 of which share (or can share) a common login (Google). This is far from as onerous as you're making it out to be.
I get that consultancies have to log hours, but that doesn't make it any less of a drag for the people who work there. And every hipchat room that you have to keep up with is additional overhead.
So you're right that 30 is an exaggeration. But that doesn't mean that they don't have overhead (in terms of time) from using these online tools.
