To quote Jobs about Dropbox - Yelp is a feature not a product.
Steve Jobs FTW yet again. I thought he was wrong about Dropbox for the longest time. But their latest attempts at "productizing" their service (Adobe / Zoom / Slack / Atlassian / Google Docs / Office integrations, "social" features, etc. etc.) have convinced me that simple file sync, which is all I ever wanted from them, is not enough to sustain a company. Meanwhile the shareholder-induced march downwards continues.
It's likely you could build a very healthy business selling people file syncing — I personally use a tiny minimalist Dropbox competitor that seems to be doing just fine. The hypergrowth demanded by investors when you take on $1.7B in funding is what's the challenge.
