Vinyl resurgence, nostalgia, rose tinted glasses. Do people really think the recording companies gave a damn about sound quality back in the day! They churned out the vinyl from a single stamper way past it's past due date, didn't care about what masters copies came from. And this not only with rock releases, I have plenty of rather pedestrian sounding classical, jazz, pop vinyl to prove it.
Some claim vinyl era was golden age of audio recordings, I totally disagree. While the masses played vinyl at home, they didn't care about sound quality and the record companies provided the requisite product. While sound quality still not an issue for the masses, just in sheer numbers audiophiles much larger cohort than in so called 'golden age', therefore, we now have many more providers offering high quality sound, where there's a market some will come to serve.
The ironic thing is these vintage recordings often offer much better sound quality than previously thought now that we have providers seeking out and offering us recordings made from original or high quality masters. Whether that is provided digitally or analog is of no consequence anymore for me and many others. The issue is all this made much of my vintage vinyl obsolete.
