My use case: movies and TV shows, streaming from mobile, PC, or smart TV with auto-downloaded subtitles and varying stream quality. Heavy use of the "watch together" feature. (Plex watch together is horrible compared to Jellyfin.)
i'm okay with that. the shows i watch don't need to be a secret. i want advertisers to know what i watch, so more of that sort of TV gets made. If Plex can make money off this information, and give me a good service in exchange for that, it seems like an arrangement that benefits us both. what's the problem?
* 20 million people watched show X-Episode 5, and
* notatoad watched show X-Episode 5 on 28-July-2023 at 8pm. We can also correlate that that they used UberEats to order Thai Cuisine at 7 pm on the same day, and that a certain group he belongs to was Y% more likely to buy the product placed within that show.
The second kind of information will be used in the future against you, to extract the maximum amount of money from you for services that "you just can't miss", after being bombarded with ads and social media influencers in sufficient quantity.
Some people consider it a problem and some people don’t.
The former is more sensitive to their data being collected and leveraged and the latter “has nothing to hide” or simply prefers targeted ads.
Some are against manipulation attempts with the goal to be parted with their money and others go all in on “personal responsibility”.
They’re entirely incompatible positions and any debate back and forth would be a waste of time of both parties.
