It depends on how you define "success".
I would consider people like Linus and Dwayne Richard Hipp and TBL to
be among the most successful people on the planet, and they write
quite a lot.
Do you call people who capture then give away a billion dollars the
most successful? I don't. To me the most successful are the ones who
create billions in wealth and capture just a tiny fraction--enough to
support their family and friends and live a good life.

Look at your own comments. My comment is effectively "people whose day job is to write, write the most". It's borderline self evident.
Your argument has devolved into: "people who write a lot are by definition successful. I wonder if there is a correlation between writing a lot and success."
It seems that "wants attention", "managing career", "promoting x" are 99% of written content these days... There was a very small window where writing really did signal someone who was thoughtful, and there are still some thoughtful writers, but it's so rare now you can almost rely on the rubric "oh they write, run".
