The point being made that Twitter was owned by rich people before Elon bought it.

Sure, but people aren't primarily complaining that musk is rich. That's a convenient 'bonus gripe' but the main issues are his political leanings and his apparent disregard for the company's workers.

Twitter was also owned by average people. As are the vast majority of publicly traded companies.

This is false, unless you mean "pension funds".

Most people do not own individual stocks. And in fact, most people do not own stocks at all. The set of stock-owning people is far from average.

Only one average person needs to own Twitter stock for my statement to be true. And the number was far higher than one.

And yes, of course pension funds count. Why wouldn't they?
