If a demographic's involvement decreases as the subject becomes more rewarding, it seems more likely to be because external forces are discouraging them rather than any inherent lack of interest.

More broadly, I question how effectively "endogenous interest" can be accurately measured without risking a lot of confounding factors from the broader society. I didn't read the original paper, maybe they tried to account for that, but I can't really see how you reliably could. People's interests don't exist in a vacuum, they're tangled up in their upbringing and society. If they'd done a similar study a century ago they might have found women having a high endogenous interest in being homemakers.
The important question is whether passionate people are being kept out of industry en masse. My gut says it probably happens on an individual basis but I don't see why it would happen systematically.
There are three reasons computers became popular in the first place: proliferation of open hardware standards with the S-100 bus, cheap computer kits, and software portability that came with Unix and CP/M clones. So anyone who knew how to build/buy hardware could program what they want on it. No need for a time-sharing system or a college degree. At that point the only limitation was time, money, and inclination.
I disagree with your final statement. It wasn't external forces artificially depressing a demographic so much as it was natural interest becoming a more prominent limiting factor.
I don’t think computing is seen strictly as a gender-restricted job like, say, mining and teaching, I wouldn’t expect much friction in the way of a young girl to be potentially interested in it and begin a career.
It just doesn’t happen that often, however. Does it have to be someone’s fault?
