It's worse because:

  1.) It's not open source
  2.) They want to charge for certain features that are free in surespot.
      (on top of the $100k they're already asking for)
  3.) They wont let you run your own server

For an encryption app? I'd almost argue that not being able to access the source code makes it a non starter. There's no way to guarantee a lack of backdoors otherwise.
