What if cloud platforms were more like brokerage firms? I can move my stocks from UBS to Fidelity by filling out a few forms and everything moves (somewhat) seamlessly.
My data should be the same way. I should be able to move all my data out of Google and move it to Microsoft with a few clicks without losing any documents or even my folder hierarchy. [Disclaimer: Maybe this is possible already and I'm just out of the loop. If so, though, extend to all SaaS vendors and all data.]
