My boss decided to use Framemaker with DITA in 2016..
We are using DITA as well, in a 10 people company. Because it is so much fun to go through XML right ?
The genius in DITa, I think, is that the guys behind it have basically created a market by themselves. I mean, the main reason we don't get off it today is because we had to hire an expert long time ago to get our layout done, and we don't want to have to redo it.
Sad times :).
