Edit: OP update the title and has my support should they run for public office.
OP is posting misleading hyperbole
This from the Plex site, emphasis mine.
We’re never going to get anywhere if people on these communities can’t act in good faith and share correct and information - not sensation. Change the OP or mods delete this misinformation.
ETA: shame on the 63 people who mindlessly upvote this crap without factchecking OP too.
What part of the op was misinfo? They DO sell the info, even if they claim it’s only with your consent
OP is claiming Plex will now SELL your personal data.
Omitting that the user must provide consent, not like Firefox or Adobe just updates T&C and forces user agreement. OP’s title is upvote seeking, cherry picking to quote certain text which makes it seem like they leave the user no choice, and leaving out the part of the text that stipulates the user does have to consent prior to the sale of information.
Moreover, the sale of data seems to be in order to facilitate the ads they show in their free movie and tv content, and even then is still opt in. The ads aren’t, but the data sale isn’t.
For posterity the full OP at the time of this post
