Dropbox and Google Cloud integrations
This is the reason why proprietary cloud services will never be as flexible as traditional programs on our computers. With N cloud services there need to be N^2 integrations to make them all work together. With N desktop programs it is enough if each of them implements a single common API (for example text bast stdin/stdout Posix API) to make them all work together.Imagine if 'cat' and 'sort' needed to implement a dedicated API to work together, and then 'sed' would add another one, and 'wc' another. This is a kind of mess that we see with cloud services integrations.
