Amazon isn't taking away "innovation" as they still offers an ad-free, higher audio quality option. You just have to pay a bit more for it. Lots of other streaming services have ad-supported plans including Disney+. Hulu, Max, Netflix, etc. Subscribers have a choice.
Today's ad-free plans are also much cheaper (adjusting for inflation) than what premium channels could cost back in the 1980s. For example, ad-free Max is $15.99/month while HBO with less content, no on-demand functionality, etc. 40 years ago was around twice that after adjusting for inflation.
