True. But even the cheapest DAP has a better UI than GoFigure. I haven't found a third party app that uses mpd that is equivalent to the Sony Walkman app or Hiby music (for example).
All iPhones have Airplay. Android phones have Chromecast. DLNA and UPnP are ubiquitous. All are industry standards that software developers can use to interface with streamers.
The HiFi world today is about streaming. Stalwort companies like Classe are putting streaming capabilities into their preamps now. Downloaded albums and curated offline libraries are losing to Apple Music, Spotify, and Amazon Music.
Chord relies on a retail store model. A flawless streaming module in 2024 would be a lot easier to sell than an enthusiast device that sorta does everything but nothing spectacularly well.
This is just my thoughts. If you use MPD, cool. As much as I want to love mpd and the microSD card, I don't. I own the Poly and 2go. I highly doubt my thoghts will threaten the survival of mpd.
YMMV. IMHO.
