If there is a short term easilly measured ROI on any action, it’s worth taking and if that means no cookies because it ensure the shareholders get a fraction of a percent return, then no cookies for you.

Their actions are not even competent by their own worldview - this kind of corporate management invariably sacrifice long term hard to measure yet large positive outcomes for the company (such as the gains from keeping highly trained personnel who stuck around because of goodwill towards the company rather than having the constant hiring and training costs as well as lower productivity from high turnaround) for miniscule but easy to measure immediate gains (like saving the equivalent of 1% of a single average worker's salary by not providing free cookies).

There really is no point in penny pinching if its going to increase employee turnaround in a domain were experience makes a significant difference.
