There's some generational drift at place, for sure. I have heard "Full Stack" to mean JavaScript FE + service layer BE in a lot of the line-of-business world. I assume it is mostly a reflection of where widespread economic activity for software development takes place. The vast majority of companies aren't writing device drivers or kernel modules.
It's kind of like reading old (pre-XP) texts about testing that refer to testing a program in a family as "unit" testing. Not technically wrong because it all depends on how you define a unit, but definitely a sign of linguistic and economic drift.
