When you say it always has worked this way what is your frame of reference regarding time? I haven’t owned a chromecast in about 6 years. However prior to that chromecast had no ads whatsoever so the idea that there are ads at all is shocking to me. It certainly hasn’t always been this way. (I currently use an Apple TV)
This actually isn’t true. You can configure sonarr and radarr to directly search indexers without using a wrapper. Most people use a wrapper so you only need to configure changes to your indexers from one place instead of updating sonarr,radarr,lidarr,readarr all individually
Still, at the end of the day a large part of what you get is what you have access too. Better indexers gets you more content
Meh, I bought an Apple TV on sale for $100 and don’t deal with ads and have all the shit you’ve laid out here ¯\(ツ)/¯
