Elon Musk felt used in the face of Trump, that's why there is an outburst from him because he felt cheated that Trump is not adhering to what they agreed. Unfortunate enough, Elon Musk is learning about Trump in a hard way that Trump doesn't give a shit about anybody who he found not to believe in his own vision and thoughts about America progress.

Elon Musk should know by now that Trump has no friends whom he will like to keep so close to him as he rules America for the second time. If Trump is good with you today, he may actually find some faults with you tomorrow. He would speak up without hiding some words openly
