Never had the idea it was getting exceptionally or even moderately hot, never saw any bulging. But when it's back I have a MacBook Pro that only has the bottom case and logic board of the computer I brought and the rest replaced for free (screen program too), after four years. Though I can imagine people that do not have a backup machine hate to wait so long.
Just wondering if I'll eventually face that issue a few years down the line, now I get paranoid anytime I leave my laptop alone on my wooden desk.
Most manufacturers will dual-source component suppliers (because a) it can drive your costs down, and b) you're not reliant on a single company to supply you), so it's very easy to have some models impacted but not others.
Even with a single supplier you can have bad batches of raw materials, a single factory line with an assembly defect, or the QA team just happened to all be out sick one day.
But device manufacturers at large scale get multiple suppliers to supply their components.
As long as it meets specification it can be used.
