Having a pejorative reference to an unpleasant person didn't hurt git. Here, Araq has taken an association that is generally viewed as slightly humorous and moved to a name with which no one has any associations, either good or bad.
In tech marketing, taking a brand that's been invested in and renaming it for no good reason is something you should be loath to do, as it throws away the value and associations that exist with the current brand.
Among the typical "good reasons" for changing the name in are: 1) the brand has been diminished by some bad news / negagive attention and so they're rebranding; 2) the brand causes confusion with other products; 3) legal reasons; 4) some other well-defined limitation that makes growth impossible.
Without having any more insight into the reasons behind this, it's hard to see whether this is a good move or the beginning of a decline for Nimrod as a concept.
