Remember, the SoundCloud direct upload feature was added with X1, and has been pointed out, the link hasn't been updated since then. The company was under different ownership and had a different project manager. When I wanted to use SoundCloud to upload an audio example for Gibson, I asked Cakewalk for a contact and they said they hadn't talked to SoundCloud in years and didn't know who I could talk to.
Instead of railing against this on the assumption that some evil person at Cakewalk is currently inserting "crapware" into the program, it might make sense to find out whether anyone - at either Cakewalk or SoundCloud - even knows it's there. It's not on the audio examples in the Cakewalk blog. As far as I know this is the first time this has been brought up since X1 was introduced, so I doubt the issue was on anyone's radar at Cakewalk.
Contacting SoundCloud won't be enough. You need to contact Cakewalk as well since presumably, the code is buried somewhere in SONAR.
