The Dropbox reply[1] was fully negative, while this one is mostly positive. It also suggested that the business wasn't viable, which this comment does not. Doesn't read like it at all, honestly.
Is cloud storage anywhere near as opinion-inducing as note taking workflows though? :) There are like a dozen new entrants each month, and so it’s probably meaningful for folks to get super clear on their core requirements. Otherwise, you’d spend all your time evaluating tools, as opposed to actually writing.
This has to be one of the most overdone comments on this site -- Not everything even slightly critical of a product is like the dropbox reply.
