Also you can literally opt out of the data sharing

For now. It's always for now. You used to be able to opt out of Google data sharing too. And Reddit's. And Microsoft's. And Apple's. And your Credit Cards... The list goes on and on and on and on and on.

Soon as a large company realizes that they can vertically increase revenue by selling your data it ceases being an option. A realization that Plex will very soon learn because they've begun to sell data "optionally" for now. Then by next year, or maybe even the year after that it'll no longer be optional.

It always goes this way. Always. I can't even think of a single antithetical example.
