You say this as if meanwhile other (presumably non-"social media addicted") company leadership has achieved similar goals.
The reality is that other companies consider SpaceX's goals to be preposterously unattainable, to the point where they don't even try.
I'm not going to look up the original context of Elon's alleged lies, but from what's written here they just sound like long term project goals rather than formal lies (implying things like malicious intent or fraud).
If anything, maybe the only reason he didn't meet those goals is due to his social media addiction.
