I doubt it. I think the primary Gibson buyer is the kind of person who thinks tuning their guitar is an unwanted burden, and a majority of customers thought it was cheesy, they would not be putting it on even more of their guitars. Gibson is mysterious and confusing, that's not the same as being completely stupid.
All the evidence I've seen claiming Gibson's QC slipping is anecdotal. Nobody, afaik, has measured a bunch of Gibsons from two decades ago, down to the millimeter, and then measured a bunch of Gibson for recent years, plotted the data, and found a wider deviation in precision from a large, meaningful sample size. It's all Internet guitar forum gardening, taking a seed like "My Les Paul feels funny, I think Gibson QC is slipping", add some water, it becomes "I heard Gibson QC is slipping" then it starts fruiting: " Gibson QC is slipping" then it all comes showering down "new Gibsons are trash!"
