Scott Pilgrim - Victim of the times

Every day a new rights holder creates its own streaming service, pulling its material from bigger ones like Netflix, requiring another monthly subscription fee. Music streaming still sounds like garbage. Media is constantly de-listed, or is available for purchase for a limited time. And yet, someone suggesting that the PS4 have CD playback is blasted and told to 'get with the times grandpa and use Spotify.'

you can no longer buy this game due to the fact that it was digital only and the license for it expired, so you can only play it if you bought it and downloaded it before it was taken down, the post refers to the fact that if the service ever shuts down or if the rights for the games you play are revoked or they expire, then your games are gone as well
