Logitech still supports the Harmony devices, for how much longer remains to be seen. I just recently replaced some that had broke so I'm good till the next device failure as long as I don't make any major replacements either.

I know I'm part of a dwindling customer base that still uses separate A/V gear and not just built-in streaming apps and a soundbar, but it seems like there would have still been a market for competent universal remotes that you could customize.

I hated how almost every generation of their remotes got harder to use and program compared to pre-Logitech Harmony. The Touch remotes were practically unusable because you had frequently used buttons in poor locations and a touch screen that you had to scroll through to find the correct soft touch button for that wasn't especially responsive, the old models with all hard buttons were vastly more usable.
