And yes consumers absolutely chose glass. If they didn't, then phones with glass backs wouldn't have sold well. Looks like the market leaders use glass back phones, consumers are happy with them and so they've purchased them. If plastic or metal or whatever other material were so important, consumers would be buying phones with those materials and reject ones that don't.
The consumers never were given the option of two devices that were identical other than build materials. This is a false premise. They chose a combination of feature sets and design decisions that were pre-configured. And that feature set includes many more important things than build materials. And that's for the few that chose at all. Marketing is still a thing, it influences choice. And most people don't choose, given that most people, at least in the US market, which is a huge flagship market, buy whatever device their carrier representative tells them to.
Premium feel isn't a ridiculous term at all. Android Central has used it to described the feel of a phone in the hand:

It is a ridiculous term because it is ill-defined and somewhat based on erroneous circular logic. The tech blogs decided that glass felt premium and then started describing glass phones as premium. It "feels premium" because it's made of glass and because those, in this industry, are somehow synonyms.
Also, not sure if you realized this, but Android Central tanked on their editorial review quality over two years ago and cannot be trusted in any way to provide objective analysis regarding the quality of devices or any components therein. There are four major long term editors that have all acknowledged that one camera or display may be more accurate, but choose the other as better. That is dishonest. They have authors writing about Chromebooks that have apparently no idea what ChromeOS is or what the pros/cons of Chromebooks are. That's dishonest.
Phil moved on and Android Central became about selling ads, not about being "the best damned Android site anywhere".
That's fine, you can disagree with whatever you want, but the notion that glass isn't premium is something I'd say is absurd.
Why can't you just say this as, "I like glass phones". There's nothing, at all, objective about stating that glass phones feel premium. It's definitely not a premium material from an economic sense. Some of the best feeling phones, in my opinion, had soft touch plastic backs - while two others had leather instead. It isn't absurd for you to like glass and for someone else to like plastic and for someone else to like metal.
It is absurd to throw all this subjective garbage out there and state is as fact, based on the sales volumes of devices that were going to sell tens of millions of devices no matter what they did. Example, Galaxy S5, Galaxy S6 Edge, iPhone 5c, iPhone X - no matter what Samsung and Apple did right or wrong with these devices, they are going to move units.
As an example, the S6 Edge was one of the worst devices of 2015 (software issues, poor battery life, resource management, major connectivity issues with WiFi, low signal strength (ironic given that's one of the main benefits of glass), fingerprint scanner issues, false touches on the edge, display not registering touches, lag, reboots, overheating, etc, etc), yet it outsold every other Android flagship, including the regular S6 - which was a better device, if only because it lost the "edge" problems. The S7 and S7 Edge fixed a lot of those issues. Yet, the Galaxy S4 outsold the S7 by 45.5% - does that mean the S4 was a better phone? Does that mean that the S4 had more premium materials?
See why sales volume doesn't equate to quality of device?
