I think it's the perception of society at the time coloring how it's received. Any normal cape with such power, in their mind, obviously would do something like that. As a warning and tool to crow to the world "Look what I can do, now imagine what I can actually do." It's a product of their times.Loved the Accord perspective. It makes sense that he would be one of the first people to get past all the confusion/misunderstanding about Apeiron. I do wonder a bit about Othello's initial appraisal. Joe and crew are already walking on eggshells in order to not freak everyone out. Why is the the initial thought that this is yet another power play. Does he need it? Why would that be the default interpretation. I mean it's not hugely out of scope, just seems odd that he defaults to yet another power move as opposed to testing new technology or abilities. I mean Joe is a tinker. The concept of testing is pretty much built in. I know I had out of context knowledge as a reader, but the idea that they might be testing something by removing a pointless annoying meme makes a lot more sense then yet another power play. Now that doesn't really make the ability less scary, but it changes the perception of CF's actions.
I want to argue that they should have left the meme gone. Bringing it back adds nothing positive. PRT and everyone is still going to figure it out, and bringing it back seems to add nothing to humanities collective intelligence.
Also, Focused (TM) Accord is scary smart. Even for a Thinker.
