it's also just flat-out unsexy from a product/MBA-brained perspective to push for something that will negatively impact metrics for your users. I ran into this when I was advocating for onboarding a third-party provider that would filter out automated/spambot email clicks thus decreasing the north star metrics our users had for engagement (even though it was truthier and would provide more accurate targeting and some of our most senior people had been advocating for for years)

the only reason I got the go-ahead for the effort was because one of our upstart competitors who was handily eating our lunch had implemented this years ago, started advertising based on it, literally pointed to the fact that we didn't do this yet, and then this was followed quickly by all of our other competitors implementing this, too. at this point we were well inducted into the illustrious halls of companies who stopped giving a shit about their core product with leadership blaming everyone but themselves for the fact that we were churning faster than we were net-new-ing

and even then it was a half-assed, resource-starved implementation that got dumped on regularly. have left the org since and couldn't be happier
