What constitutes Usage Data. Is it sharing the posts I view, communities I subscribe to etc?
Does paying for a premium version stop this data being collected?
You’re free to use any app you want. Some people prefer free open-source apps, some people want to pay for a quality app. It’s good to have a choice unlike with Reddit. I don’t understand people complaining about having additional choice because they don’t like it.
Some people want to keep the Fediverse ecosystem completely pure in terms of free software, and they will yell at you if you don’t play along.
