@polotek The "affordances" are removing the context and control from the original author.
Which may well be necessary and justified. As I said, it's something missing from masto. But it's not just about the way the feature was abused on Twitter.
It's also about giving ownership to users as authors & owners of their content. QT lets me take your content and use it to drive a conversation that excludes you.
Imo that change of control is at the heart of the toxic behavior associated with QT.
