In general it boils down to "the distributed storage is buggy/not performant".
The standard experience I want as a user is that my "cloud" files should be treated like my "local" files. However, in practice this is not the case. There are constantly syncing issues, files go missing from device or another, old versions appear/disappear randomly, the syncing server can't connect for a very long time (say upwards of 20+ minutes), etc. etc. And of course as Murphy would have it, this usually happens around the time where you critically need to share files across machines with a client or something. It's just generally a really frustrating experience.
