I got an email with a link to a page that let me download PDFs for all of the magazines I had in the service ("all of the magazines" being 4 of them that I got for free in 2012, but the point stands). If I had pirated those magazines, I doubt the quality would have been as good as an official PDF from the source.
Lately it seems like there's a mandate at Google to make it a pretty easy experience for users when they inevitably shut things down. Between this (easy portable download of all my content) and Stadia (total refund of everything), it really seems like they're trying to lessen the risk of investing in their new products. I can't say I'm totally convinced, because it's still obnoxious and inconvenient, but it's a decent start.
