My comment assumes no such thing; the major difference between editions is the requirement in 5th for a skilljack; in SR4, a hot-sim modified commlink was enough.
The linguasofts themselves only jumped a little bit in price; the steep entry point in SR5 comes from the now mandatory Essence loss and cost of 20k per rating for the skilljack.
Essentially, if SR5 had kept the requirement of a hotsim modified commlink from SR4, the slight increase (well, double) in cost of the linguasoft itself would have been tolerable. The requirement of the skilljack is what kills linguasofts for Awakened and/or Emerged Face type characters (Essence loss = magic loss, which very often means it won't even be considered), and for a lot of characters who are resource heavy in other respects (street samurai, deckers, riggers).
In short, in the span of 3 years in-game (2072 to 2075), linguasofts went from being "prolific" (in other words, abundant, something most people could afford even on their own), to being completely out of reach for nearly everyone except the corps. That might not be particularly out-of-character for the corps, but it is hugely jarring in terms of game balance.
Adepts with Linguistics are now kings of faces, if you deal with multiple languages. The mere fact that some tables have chosen to entirely handwave language should be an indication that this rule change did not have the intended effect (unless that was the intended effect, in which case why even bother with the whole languages section in the book?).
