For most users it seems fine, but as someone with an interest in researching historical software, I do find some of this stuff a bit troubling, unless there's a way to turn it off. It's getting harder to install and use old versions of software, without resorting to running things in carefully controlled snapshotted sandboxes. Also a problem with games, which sometimes significantly change gameplay with patches. You used to be able to archive the original binaries and then also archive each incremental patch, but auto-updates (and other things such as DLC) are making that all tricky.
