It's literally written by an individual that is male. Let's hope he knows what gender he is.

Then they should have used "How THIS technical co-founder spends HIS time" -- by using "a" instead of "this" he implies a generality.

That was my original thought as well, though I can see the other reading now, too.

So while the title could perhaps have been better worded, I can believe no conscious bias was intended.

It doesn't imply anything, it's just an ambiguous construction.
