The original spirit of the term "bloatware" has been lost at this point, as people regularly use it to describe anything they do not like regardless of the utility or usage that other users may find therein. The term was originally coined to describe third party software that was loaded onto PCs (anti-virus, printer ink deals, etc) on top of the stock Windows OS image after the fact. This typically took place in retail settings and had no value to the end user. Do I agree that stock apps can't be deleted or hidden? No. Do I consider a new service or feature set being added to a stock app as "bloatware"? No.
I agree, something becomes bloatware only if it degrades the usage of a device/product. Adding another application like Podcasts only has a minimal effect on the usage of an iOS device (one-time need to move it to the last page or folder on last page & 12 MB of storage, the latter being equivalent of four images taken with the 8 MP iPhone).

It's repetitive. They already have iTunes Radio in the OS. Additionally, it's not a feature. The article says that it would remain a paid service. Don't put anything on my device by default that requires me to pay for it to work.
It's like installing freemium apps on devices I've already paid for.
iTunes Match is a paid service, renting movies is a paid service. Yet these are still features of iOS. Hell, the phone app only works if you pay for a phone contract.
Having an app that does nothing without paying would be awkward, I agree, unless it would be something essentially everybody would want to pay for, like a cell phone plan.
