I'm 50/50 on that - either they genuinely were caught out by it or are very aware their reputation couldn't take the hit as they dealt with it very quickly and decisively when it became news.
I'm going to lean towards the former as I have some experience of interacting with MSI and have never seen them deal with matters quickly or decisively.
But who knows, maybe after the MXM fiasco they have employed a PR firm that is competent.
Just in case you are reading this MSI (ex MSI too) - Reneged.
