The cloud services of big tech cos can be counted on to store things cheaply or for free long term, for now. I do not trust them to hold onto anything or preserve access to it for 50 or 100 years. IMHO, people should be their own digital archivists for the really important stuff on those timescales, to avoid the risk of important data being discarded or held hostage by profit motivated companies at some point down the line we can't see coming yet. "The cloud" is young in terms of human life, and the rules we live by are volatile on that scale, shifting with transfers of power and depletion (or discovery) of important resources.
