Cumulus is going through bankrupcy so the bean counters are trying to avoid a liquidation of assets or a 10c-on-the-dollar fire sale. In any case, radio is not being "enshittified" but its market is gone/fading with the boomers. The Greg Papa and Lamont contracts are just not affordable now so out they go. Ads are now more local like plumbers, hvac, lawyers, etc. since Trump ended USAID and their NGO funding. There is also RFK/HHS talk of ending big Pharma drug ads on TV/Radio too which would further gut radio's ad base.
BTW, the EV crowd (e.g. Musk) wants to end AM radio in cars because it is expensive and shielding is heavy for large DC motors that don't interfere with AM radio band.
