What do you mean by this? AFAIK they added MySQL wire protocol compatibility long before they added Postgres. And meanwhile their cloud offering still doesn't support Postgres wire protocol today, but it does support MySQL wire protocol.

fwiw MySQL has been extremely unpopular on HN for a decade or more, even back when MySQL was a more common choice for startups. So there's a bit of a self-fulfilling prophecy where MySQL ecosystem folks mostly stopped submitting stories here because they never got enough upvotes to rank high enough to get eyeballs and discussion.

That all said, I do agree with your overall thesis.
