This seems like a post-hoc justification. The LDS facility services had several lifetime career workers they fired after implementing this policy, and the congregants rarely kept it as clean.
I thought the same thing. I played basketball on 100s of Saturdays in the 80s/90s and still think about the kind janitors that cleaned multiple buildings on Saturday. Many lost their jobs due to that policy change and it seemed like nobody realized the people lost their job because of it.
