So if I understand it Signal has your phone number but only logs sign up date and last activity date. So yes they can say this person has Signal and last used it on date X. Other than that no information.
Matrix doesn’t require a phone number but has no standard on logging activity so it’s up to the server admin what they log, and they could retain ip address, what users are talking in what, rooms, etc. and E2EE is not required.
I think both have different approaches. I’m just trying to understand. On one hand you have centralized system that has a standard to minimize logs or decentralized system that must be configured to use E2EE and to remove logs.
Well there is enjoying an artists music and there is supporting an artist and defending them. But you have to decide when to cut off an, “abusive relationship”. I can hold a person and artist in separate spaces. A love a lot of music, literature, art that was created by terrible people but try and avoid giving those people my attention and money. Other people have said that while an artist creates, its not their art, it’s ours. Perfect example is Harry Potter books. I would say that people’s experience and enjoyment of the books is not JK. Now the tough decision comes when you want something created by an artist/company and you have to support them for your own enjoyment. That is the line we all consider. Just trust yourself to find it. Nothing is truly just in this world but we shouldn’t stop trying.
