I remember I was using Google login to login to my Dropbox and in the last year or so Dropbox started asking me to access my contacts in Google. I would always deny access and still manage to successfully login. Yesterday I tried the same but with no luck. I contacted Dropbox support and this is their reply:
> I'm afraid that is not possible at the time. I apologize for any inconvenience this may cause.
Interesting that they chose this route when users are getting more and more privacy-aware.
I had a paid pro account at the time.
I actually had a conversation with a product manager; I checked the yes you can contact me when I cancelled my account. They simply refused to admit that an upsell was a advertisement and that disrupting my workflow on my paid, professional account for an ad was wrong.
The other interesting thing about that conversation, they could not understand how a sole proprietor would see no benefit from collaboration tools and kept making up bizarre scenarios where I could use them.
I actually asked them if they were a product manager or a salesperson at one point.
To Dropbox's credit, that product manager didn't try to retain me, they were genuinely trying to figure out why I had quit; they just couldn't grok the reason.
