They will collect or probably are already collecting. Even if everyone defederate from Threads, they can and will open a secret instance and get all the data without anyone knowing it
We have interoperability for emails but most people use gmail/microsoft , so you could be tracked even if you use protonmail
But does he know that you actually only work 2 hours out of you 4 hour work and 8 hour shift?
OK so let’s tell the regular user “hey come to lemmy, but don’t forget to keep multiple accounts because here everyone can spy on you”
That’s not a good message
Yes, but like I said, most people won’t be on those services so they will be able to collect most of your data anyways.
Here at least on Lemmy is even worse, because they can get everyone’s data even if you never access theirs instance or they could simply create a shadow one to get the data without anyone noticing
