I guess one metric would be that whenever a tech website reviews or recommends a gaming laptop, an MSi is often, though not always, recommended to readers and this unfortunate episode regarding the GT72 and GT80 is never mentioned anywhere. For some people, MSi became known in the first place a few years ago because of the strong challenge they posed to Alienware in the gaming laptop market, especially when they released the Dragon edition, though luckily several other challengers have emerged since then.
Another would be, for better or worse, noted websites do recommend them still as a top manufacturer such as Engadget:

When this first occurred I spoke to various tech websites and asked them to take on the story, was advised that if anything negative was reflected about MSI, MSI would not provide test units to review. Thus losing them readership to competitor websites.
