@Dirk@MrScottyTay Also I think that one should ask the question, what Meta could do with the data and what it is doing with the data of their users. For their users they use the usage data to present them a feed that the users appreciate. Also they use it to place ads inside of their apps. Also they use the data to serve you ads outside of their system on ad networks that use data from Meta.
All of this is technically not possible for Fediverse users.
