That's really what it is to me too, and I'd consider myself pretty technical: A podcast is what I can listen to in the gym or on my bike without missing anything important on the video.
The only difference to an audiobook is that Podcasts are usually free and often (but not always) in serial format, but these boundaries are blurring more and more.
That said, I do definitely prefer open RSS distribution than something like "Youtube for Audio", and I'm glad there isn't any such thing (yet), but I wouldn't not call a podcast exclusive to Spotify, Apple etc. "not a podcast", just an annoyingly-distributed podcast.
