I think there's some cases where the medium is part of the experience, Radio Caroline in the UK are a former offshore pirate who used AM by necessity in their heyday (they'd anchor the ship just outside of British territorial waters to circumvent the BBC monopoly). The revival station worked hard to convince Ofcom to let them operate on AM given their historic connection to the medium, but they were granted a licence and are probably one of the few AM stations in the UK not in terminal decline.
I'll miss Five Live on 693 kHz, I grew up coming back from Watford games with it on in the car crackling as we went under power lines. Test Match Special on 198 kHz longwave is already gone in preparation for Droitwich's closure.
The AM radio community is definitely small and kind of niche, but I always had more fun listening to Coast to Coast on a late night road trip than I ever did listening to FM.
