I had a pop up on my MacBook after the iTunes update explaining the changes to me and providing me with the link for new instructions for transferring custom tones, I don't think they'd have done that if they were trying to sneakily trick people into buying ringtones. You do know nearly every iPhone user out there has that same damn default ringtone and couldn't care less don't you? You're talking about a very niche thing to do. Not everythings a conspiracy theory you know....
Edit: I've just given it a go using a custom tone maker on my MacBook. Dragged on dropped straight onto my phone. Less steps and even easier than the old method, took seconds. You can delete/manage them from iTunes that's separate from the content on your phone. Literally the only thing 'missing' is having a tab/library for your tones within iTunes. I think you're getting upset over nothing.
