Any company with sufficient size will fail to incentivise the things they claim at the top, unfortunately the impacts of decisions (especially during austerity) are poorly understood, so even the supposedly best intending will fail once you reach a size

What products do those two companies sell?

Let's Encrypt and Google Trust Services are both CAs.

LE is of course, a non-profit, so maybe this doesn't apply there.

Google Trust Services operates under Google, and is technically "for profit". But no, we did not put profits over security.

Are you referring to google trust services? I don't see how that applies to let's encrypt otherwise.

go make a cost analysis of crawling the entire internet once or twice a day on http vs https and report back

lol are you claiming that https is done to make web crawling more expensive?

Wild.

the most pressing to google at the time was telecom abusing monopoly of mistyped urls to dictate search engine of their choice. but that too.

I'm deeply confused by this?
