OpenLava is a GPL'ed version of Platform LSF 4.5, under the GPL2. It was forked by Platform LSF as an agreement with Redhat in 2007, before IBM bought Platform LSF.
According to the project leader, David Bigagli, IBM has decided to target the project by submitting a DMCA notice for the current version of the program on Github (https://github.com/openlava) and now asks that the website hosted on AWS be shut down.
What can these guys do?

Update: apparently, on Reddit, there is the guy that was directly involved in the process of releasing some of the Platform LSF parts as GPL:
