Like elon or not it makes absolutely no sense to compare social media with effectively newspapers, they're completely different things.
The only comparison I guess you could realistically have is zuckerberg, but even then it wouldn't work very well.
The real comparison is that the owners are billionaires and giants in their “industries” in some fashion.
Elon forgot capitalist step zero: Choose profit before ego.
That he is a bad capitalist will become apparent at a long enough temporal scale..
