My response to this site as someone who has had a paid Dropbox account for years:

Oh no. Oh... no. follow link to dropbox.com Ugh. What happened?

I'm now under the impression Dropbox will go out of business and I need to explore alternatives.

Edit: I think I identified what makes me intensely dislike it. The color scheme and design screams "This is no longer for you, it's for hipsters."
