The issue I take with statements like that is that they are saying one thing while doing the opposite. This document [1], for instance, shows that YouTube knew as early as April 2025 that infinite feeds of short form content can "displace valuable activities like time with friends or sleep", but that hasn't stopped them from aggressively pushing YouTube shorts everywhere.
The most charitable interpretation I can think of is that there are two factions, one worried about the effects of YouTube in teens and a second one worried about growth at all costs. And I don't think the first one is winning.

There are plenty of examples that the mental health people aren't being completely steamrolled. Parental controls allow you to block Shorts for your kids. That doesn't sound like a "growth at all costs" mindset.
Growth at all costs should be no one's priority.
so of course "growth hackers" (or whatever the folks responsible for growth are called nowadays... other than CFOs and CEOs), simply they are the ones whose judgement and "worldview" regarding whose responsibility is to manage the negative consequences of their increased revenue is very skewed, in other words they mostly have elaborate self-serving explanations (excuses)
and many times that overlaps various user freedom arguments, arguments against paternalism, etc...
