This, 100%.

I've seen the same scenario - someone with limited vision, next to no feeling in his fingertips and an inability to build a mental model of the menu system on the TV (or actually the digi-box, since this was immediately after the digital TV switchover).

Losing the simplicity of channel-up / down buttons was quite simply the end of his unsupervised access to television.

Channel up/down doesn't scale to the amount of content available now. It was OK when there were maybe half a dozen broadcast stations you could choose from.

That's only if you want to watch specific things; some people just turn it on for entertainment, and change channels to have a spin at the roulette wheel for something better.

This is ahistorical. If you had cable, you had 100+ channels, and there was no difficulty in numbering them and navigating them through the channel up/down buttons. There weren't even only half a dozen broadcast stations in any city in the US at least since the 50s - you at least had ABC, NBC, CBS and PBS in VHF, and any number of local and small stations in UHF.

The thing that didn't scale was the new (weird, not sure why) latency in tuning in a channel after the DTV transition, and invasive OS smart features after that. Before these, you could check what was on 50 channels within 10 seconds; basically as fast as you could tap the + or - button and recognize whether something was worth watching; changing channels was mainly bound by the speed of human cognition. I think young people must be astounded when they watch movies or old TV shows where people flip through the channels at that speed habitually.

		> new (weird, not sure why) latency in tuning in a channel after the DTV transition, Because with analog signals the tuner just had to tune to the correct frequency and at the next vertical blank sync pulse on the video signal the display could begin drawing the picture. With digital, the tuner has to tune to the correct frequency, then the digital decoder has to sync with the transport stream (fairly quick as TS packets are fairly small) then it has to start watching for a key frame (because without a keyframe the decoded images would appear to be static) and depending upon the compression settings from the transmitter, keyframes might only be transmitted every few seconds, so there's a multi-second wait for the next keyframe to arrive, then the display can start drawing the pictures.

		I still watch OTA DTV. Tuning is instant. Maybe it's slower if you are on cable and there's a few round-trip handshakes to authenticate your subscriber account. I'm pretty sure there's a lot of round-tripping going on with the streaming services I use through my dongle. They're always slow to both start the app and to start any actual streaming.
