Not exactly true.  For modern electronics, yes.  In the past for electronics, 
and still current for industrial and transportation applications, there is a 
cross-linked adhesive, typically acrylic, used.  Adhesive starts out as a low 
tack removable, and the cross-linking helps to keep the adhesive on the 
protective film and prevent transfer to the protected good.

Over time the two surfaces become more intimate, and the adhesive builds in 
strength.  Therefore, the longer it's there, the harder it is to remove.  My 
guess is that the cross-linking also boosted the chemical resistance, hence the 
reduced effect of solvent now.

Heat to soften and letting solvent soak on the surface for a while are the best 
chances.  Maybe a light sanding?
