The displays at least on earlier Touch Bar MBPs felt quite flimsy to me, but it hasn't seemed to be a particular issue before now... I wonder if the screen assembly is different despite it being the same chassis since 2018/2016? Or maybe a different glass is being used, or they've had a bad batch of glass.
My thoughts, as well. This chassis design has been in place for years and one would think if there was an inherent design flaw, we almost certainly would have seen it with the Intel models (especially since the Intel MacBook Pro 13" is still being sold).
