I don't see how that did any harm, and it let the soon to be former staff and whatever listeners remained let off some steam.
Going in the other direction, a friend of mine was listening when the Christian AC format on 94.9 in Dallas/Fort Worth was changed to a high energy Top 40 format at KHYI, Y95. After the last Christian pop song was played, he told me that a voice came on and said "That's enough of that crap", after which the Top 40 music started.
Needless to say, Y95 has been gone for decades, the KHYI call letters are now on an Americana/country rimshot in the market, and Christian AC has been back on 94.9 for quite a few years.
