There are actually two separate and distinct reasons for some of us to feel ripped off:
1. We have lost 'Ad-Free radio' that was advertised as part of our iTunes Match subscription. This issue can be somewhat remedied by cancelling the subscription.
2. Apple TVs, 3rd generation and earlier, have lost their only way to play ad-free music. ITunes Radio is STILL an advertised feature of 3rd gen Apple TVs, see
HERE. The only remedy in the 'Inernet radio' channel, which offers ad supported music. Not a good replacement...
I own two 3rd generation Apple TVs that were used to play ad free ITunes Radio music into the rooms where they are located. There is no similar replacement on this device, since Pandora, Apple Music, Spotify and other music services are not available on 3rd generation Apple TVs. I can still play my own music library though.
