+  \item Initially attracted the community of contributors frustrated
+    by the RTLinux legal issues.
+  \item But only actively maintained on x86. Very low activity on the
+    mailing list.
+  \item The community of users and developers switched to Xenomai.
   \item May offer slightly better latencies than Xenomai, at the
-    expense of a less maintainable and less portable code base
-  \item Since RTAI is not really maintained on ARM and other embedded
-    architectures, our presentation is focused on Xenomai.
