"We control tne horizontal, we control the vertical..."
"Google's web capabilities project ... is an effort to add APIs such as native file system access..."
So we will no longer have any control at all over our computing devices or over access to our files?
All these vendors want to [a] snoop on everything we do and everything we save and [b] regularly extort us for using our kit and processing our files, backed by the threat of losing the lot if we don't pay up on time.
Added to which, many of the "cloud" offerings are, shall we say politely, not well designed. For example, I've just been helping a guy recover a massive and very important photo archive from OneDrive. It insists on zipping every download so each folder of photos at camera resolution resulted in at least a 4GB zip file. After almost four hours to download, one of these was a complete write-off as we lost the link a couple of seconds before it finished, rendering the zip file unusable.
If zip could optionally be turned off (apparently it can't) the problem would not exist as only one photo would have been lost in case of link failure. In any case JPG files hardly reduce in size when zipped so it's pointless. But of course the "service" provider knows best every time, even if their decisions cause you problems.
If I were cynical I might conclude they don't really want you to recover your stuff, as that would reduce the need to keep forking out.
