"Purchase" doesn't quite reflect modern TOC, I believe the more exact term would be "pay a premium for a longer term license to view video content that is revokable at vendor's will; neither continued availability nor immutability of the initially licensed content is guaranteed".

I would really prefer to pay per view instead and retain a high degree of control over my hardware and software configuration as well as having a reasonable choice of options in terms of video quality, various subtitles and audio tracks.

Ideally I'd be able to buy audio track or subtitles separately to combine with the video content for viewing (plug-in), then there would be a robust market of competing translations.
