But this post is using the word “invent” instead of “found” to make sound like Elon just bought the companies (like he did with Tesla and Twitter) instead of the technically correct statement that he bought the smart people who made these companies possible.

You don’t use the word “inventing” about forming a company, you use the word “founding”

No shit, Sherlock, that’s the point: it’s emphasizing the difference between providing the funding for a new company and providing the innovation that makes it successful.

Edit2: I think this post might just be made by one of his sycophants to chip off the credibility of leftists or other people likely to share it.

You’re entitled to your opinion, but I think your pedantry has gotten the better of you. I don’t believe that most people would be at all bothered by that tiny bit of lexical artistic license in the service of brevity.
