Earlier quoted context omitted.
It’s so gauche and embarrassing to see a serious executive announcing a principled career change through Twitter. “Tweet 6/12” ... a red flag should go up somewhere. Can you not buy a domain and link a short paragraph? This isn’t an issue related to Threader or visual reconstruction of tweets. Rather, how did society get to a place like this? It’s bananas.
Can you elaborate why it's gauche? I'm assuming the intent is to share on the platform that has the audience you are seeing to share the message to. It's not user friendly to direct people to another channel.
Twitter lacks both document authoring features and professionalism context for anything like an announcement like this. It comes off like an out of touch person trying to stay “fresh” or “with it” shoe-horning a dry press release comment into a medium people use to laugh at cat photos. Even official Twitter accounts and journalists have the sense to link externally to more important matters. It undermines credibility to put those matters directly on Twitter. A single short tweet of that type is bad enough, but a 12 tweet thread is further forcing long discourse into a platform built to avoid it.
