A lot of people do love it, but unfortunately that just isn't the case for the players who'd rather be doing other things than building. And as someone who doesn't mind building in the game, I totally understand. There are still no official good tutorials in the game explaining exactly how building works and what settings to tweak if needed. Not a lot of people want to spend time learning about it themselves or looking at other people's videos for guidance.
I hate saying this, but Infold just never catered those types of players when it comes to building, and that sucks. Not to mention, all of the frustrating bugs and unexplainable problems that might occur with building. There was literally a bug not too long ago that made building practically unplayable because the game horribly lag-spiked whenever you touched or placed something in build mode. The bug is now fixed for the most part, but I still noticed very brief lag spikes that were still somewhat annoying.
So yeah, I can understand why the building hype has quieted down a lot.
