No it's not at all. It's something he's done since the very beginning. You can go back to the 2000s with the first few public interviews he's given since starting Tesla and SpaceX after accomplishments (first few years of both had no accomplishments to redirect praise) and he's constantly redirecting to the team. It's always driven me nuts how many people misquote him and consistently ignore all these redirections of praise.
I learned through that attempt at going back through his tweets that, as you pointed out, Twitter is really not built for that. I guess I hadn’t really put much thought it in at the time, was just on my phone, curious about SpaceX, and thought it might be an OK way to get some updates.
Hopefully that makes at least a bit of sense…
