Because they are in a dominant market position. Honestly, it's your fault for buying a console - you knew you'd be at sony's mercy due to the monopolistic nature of consoles. The cost of switching to the one comparible console option is so great, most people will not bother unless sony's issues become too great - and network speed is presumably not a deal-breaker for enough people for sony to care.
So you will continue to suffer abominable download speeds on your PS4, because the cost of switching is too great for most. Basically, suck it up.
I hate to get all PCMR on you, but this is why everyone should game on PC. If my steam purchase downloaded super slow, I could simply get a refund on steam (an automated process) and purchase the same game on GOG, or on Humble Store. Sometimes Origin or Uplay. PC means freedom, or not being at the mercy of a single uncaring corporate entity.
