I dont think you get it. Nothing done by Apple is random, its all about the mighty dollar.
They didnt just change the way you have to do it.
If I didnt search online and find the workaround I would not be able to sync my ringtones since the option is not there any more on itunes on my computer.
Most people will not just figure it out on their own dont you think? Because nothing about this "new way you have to do it" is intuitive or easy with no option to remove ringtones.
Why do you think Apple just made it extra hard and near impossible to sync your own ringtones?
Because its better for the user and more streamlined? Give me a break.
Its intentional and they might remove the option completely with a future itunes update.
