The problems you're describing are independent of whether software is open-source or not. There's plenty of proprietary software with no support, no training, nobody to blame if things go wrong, with terrible UI design, no way to get new features you need, no marketing, and no guarantee of updates. Any random Computer Associates product from 1999 would qualify for nearly all of those, as would most custom software, and that's before we even get into proprietary shareware. And there's plenty of free software that's at the opposite end of the spectrum.
