I have three reasons

First, and the biggest, is you have to trust these scum. That they are doing only what they say they are and won't decide to do more in the future. Are they being audited? What are the notification capabilities and contracts when they decide to look more invasively?

Second, you have to trust their programming capability. Who knows what update / reporting capabilities it has, and how well secured it isn't (every time Project Zero looks at stuff like this they find holes. Every. Time.)

Third, the lack of transparency. If this is so awesome for me as a consumer, then these companies should prominently disclose it.

Scum? You're trusting hundreds of companies with your data everyday already. Redshell is regulated by EU as a data processor just like these other services.

Lack of transparency? Go check out redshell.io right now and see how they open up about everything they do pretty damn clearly.

Multiple devs who use redshell announced its integration in patch notes. What more do you want?

An explicit opt-in when said devs made the integration, and the game dev to not send tracking data be default.

Not expect every user to read all the patch notes go to a third party website and fill out an opt out form, and then pray the third party to honour your request. This is slightly different from expecting a game dev to do so - tracking is not their sole business model after all

Actual, prominent notification, not something hidden in the patch notes.

Facebook is regulated as a EU data processor too. And look what that's done (very little so far.)
