Personally, I think a factor is there’s been a shift by companies in general to not make things as obvious to repair. My dad has a unibody 2012 MacBook Pro and the book literally tells you how to open it so you can service it by upgrading the RAM; a far cry from the situation today.
Older tools were held together with some common screws and were all built the same, so there wasn’t too much concern from the layman popping one open to clean it out to service it. Modern power tools just don’t look like you should be opening them, as the screws are completely hidden, they’re hard to open comparatively, and its usually the battery that goes anyway, which can’t be replaced when it’s been discontinued.

Until the late '90s, almost everything Radio Shack sold came with a schematic included in the user manual.
Today, everything is glued together with no non-destructive way to even open it.
