Are tuners still popular

Nope. I never had good FM reception - now listen to my stations ( and around the world ) on the internet.

Even for the astute audiophile the are different kinds of music, one of which is Phil Music, the stuff in between listening sessions.  This is the background music of life.  Radio is prime source of this.  Radio is also a powerful source of local information useful to daily life (try the weather of traffic), and of course radio is a good source of what you have never heard before, or a reminder of what you have heard but forgotten.  

While AM radio is struggling for relevance in modern life, FM still is as it is portable and timely.

I doubt you will see it go away but more likely become more personable.

I’ve been helping a friend run a small, low powered station here in town. We hosted dance parties to raise the money we needed to get started.. I know of at least 5 people who have purchased tuners to listen. So yeah, there’s still life in radio, especially since the FCC opened up the spectrum to low powered, local stations. Much more relatable, no commercials, our community is loving it

My analog tuners have been replaced with music streamer/internet radio

If you own a tuner and derive enjoyment from it, who cares whether tuners are "popular"?  I have a Luxman T110, which was once highly touted and now seems to be worth about 75 bucks.  I probably should use it more than I do.
