Elon was actually at a hackers conference recruiting for spacex and Tesla. So the hqr tweet is aimed at them, not at the broader populous.
The short-shorts humor is about “the deal” actually happening, which his tweet insinuates to me. The “funding secured” and such, so he’s having a little fun with those people who’ve cheated, pillaged, lied, and stole to attempt to destroy a rapidly growing new American car company and new energy company employing over 30k (mostly American) people and counting.
I have observed three very active and highly placed Trump movement operatives openly use their political platform to advocate and influence others for the benefit of their short position in trading Tesla, which is ironic in itself, since “America First” and all. I’m not political, but you call it when you see it.
This is the exact type of manipulation, hypocracy, and blatant extortion of a political following (or of any unknowing people) for selfish gains that Elon would like to extricate from Tesla mind space by going private.
