This kind of statements bother me because they are simply not true. You can have "tangible" controls (physical knobs and sliders) with digital signal processing back-end and I bet you that you can't tell the difference in a double blind test. This is the same bullshit that is thrown around by designers, artists and any kind of 'aficionados'- cliches of romanticization of the analog.
Oscilloscopes went full digital in 90's not because they were worse than analog counterparts. These are precision instruments that benefit from digital processing. Don't get me wrong - I own an analog oscilloscope for different reasons, i.e. I was fascinated by how things were done back in the day which I believe is the central theme of this thread. These analog motion graphics machines are amazing - NOT because of 'infinite resolution' but the process of creating art: Oscillators, scan rates, amplification, etc.
Kinda curious example to bring up; I was under the impression that early (ie 90s) digital oscilloscopes were quite seriously compromised, especially in the UX department.
It's not even that it is, or was, impossible to make digital equipment with responsive interfaces. It's rather that the easiest way to do it often involves a delay.

In high school physics we were doing some experiments around pendulums and used metronomes to measure the period; I remember the teacher telling us about a former student of hers, a concert level musician, who could keep a beat in perfect timing without using a metronome at all.
And yes, digital audio typically inherently has some latency due processing typically being based on some buffers. Sure, you can try to make those buffers smaller but that is not always so easy to do.
On a full duplex phone call, you can tolerate quite a bit of latency, upwards of 600ms, provided there is no echo, as soon as echo is present, we notice the latency - but even on echo free calls, the longer the latency, the more likely both parties will end up speaking at the same time.
I do agree about how annoying it is to see people misled about the quality of digital products, though, particularly for consumer goods where people aren't interested in the implementation details anyway. I'm not about to splurge on an analog amplifier for my speakers, and I don't think most consumers should bother doing so either (again, unless they really appreciate the implementation details of an analog circuit).
Now I think some folks want particular analog sounds. There are digital replacements for most of them, and of course they are a lot more convenient, but they don't always sound _completely_ authentic. If you want the tuning instability, noise, distortion, etc., well, go ahead and maintain an antique synthesizer. It's kind of a pain, but if you really _must_ have the original sound, go for it.
What I miss is the quality of the actual keyboards. I had a chance to buy a vintage Yamaha KX-88 keyboard some years ago and I chickened out, and I regret it. If I had bought it, I'd probably be still enjoying it alongside my vintage DX-7.
The point, which you might have noticed when using digital and analogue oscilloscopes, is that delays come naturally in digital equipment. You _could_ probably get rid of it in all or most applications if you really made a point of doing so (and that would be very nice), but that is often not done.
There are good technical reasons to go digital, and in theory, no drawbacks. Yet, is pisses me off that I need to boot a motherf%*$cking oscilloscope and wait several seconds.
I have spent the first years of my career at an AR company whose constant worry was to lower latency and maximize increase rate. I know this stuff is hard and as an unrecognizable handicap I now have an eye for all the small glitches in video: occasional fps slip, brief shearing, dropped frame, etc... I have yet to find a giant advertisement screen that had none of these.
Most people think 60 ms latency and 30 fps is good enough but let me tell you, we had a very different kind of reactions when we had less than 16 ms of latency (i.e. "one frame") and 60 fps display (or rather that annoying 59.94 Hz that TV asked us and forced us to feed to the software through a specific clock plug).
When people talk about the "analog feel", that's what they mean: full fps (usually 50Hz in Europe, 59.94Hz in US an Japan) and <16 ms latency. No glitch, no shear (though analog system can shear) and no framedrops. Very few digital systems actually live up to that standard.
