Their UX has become worse, questionable design choices, and 2 GB limit is almost a joke. Chances are, if you're in the market, you just use something like Box which provides a lot more value for free.
I'm a long time user and when people talk about the UX (many, not just you), I am always puzzled. What UX are you speaking of? For me, Dropbox is just a folder on my hard drive with no real UX to speak of. It's the ultimate "gets out of my way and just works". Are you talking about the web site?
There's a challenging to use UI that has become part of the installation process on recent updates. Most of the time it tries to advertise to me that I need to use Dropbox Paper rather than making it easy to copy/manage folders from external sources. (I need to do a bit more than just manage files/folders, like handle external shares, so I have to use the UI they provide for doing this.)
