In general, researchers don't try to understand second-order effects of their pet theories, because the consequences of the theories are not relevant to the theories being true or false - it's an "is-vs-ought" distinction.
This is an article that observes and describes aspects of how X influences Y. The question whether Y and its implications are good or bad is orthogonal to that; any discussion about whether Y should be hastened or slowed down would be simply offtopic. Discussion about which other factors would hasten or slow down this effect would be relevant though.
I'd go even beyond and argue that researchers should explicitly and intentionally avoid considering such "second-order effects". Let's assume that this research is true (perhaps it's not, I have no strong opinion on that) and, as you state, acknowledging that "this research says we're not going to lose anything on the quality side anyway" will cause some unwelcome consequences. In that case, what should we do about it? Should we avoid saying the truth because we don't like it? Should we lie and say "oh, we are going to lose on the quality side" because we don't like the second-order social effects of acknowledging the truth? I'd argue that allowing the social consequences (how things ought to be) to affect your view of reality (how tings are) is anathema to the concept of science, we should instead strive for objectivity even if (and especially if) we don't like what the looking glass is showing us.
