... I think not!
j/k
I listen to quite many podcasts, I subscribe to new ones at times, and stop on others. I almost never watch conversations etc with video as I find it boring and also a waste of time. Audio-only is great when doing other stuff that does not require much attention. Or when I am so fatigued and/or pain I am too tired to read. So podcasting is an important medium for me. I used to listen to radio, but it is mostly shite. But I digress.
It seems more and more podcasts are also going (also) video, which does seem pointless. Only advantage may be it can be easier to hear what they are saying, I guess. Or maybe if you are watching/listening together with other people? Televison with face mask? I come across a few who call themself "podcast", but are only on youtube, which is sad. So on rare occasions I download a youtube video and convert to audio. And consume it as a podcast (which the creator/s/ say it is).
I have been using some addon to Firefox for that. It stopped working and the others I saw in FF's addon "repo" seemed rather... well I wouldn't install those. Today I searched in Ubuntu's repo and found youtube-dl, which I used years ago, I think. It worked fine, with the rather nifty flags -F and -f. Nifty for an audiocast listener.
Now, a few hours later, I just stumbled upon news that it has been taken down from GitHub. The name might be a trademark infringement but the code/application is hardly a copyright one.
I do not use git, nor GitHub, but when news came a few years back that Microsoft acquired it, I thought to myself that if I was on it, I would leave it. It never turns out well.
