Almost every time a new product comes out, there's the headlines of "[Near] Impossible to repair, likely to kill repair shop industry", and it does not.
It does usually mean new tooling, new skills, and some waiting, but so far it's not a death of the industry. When we started seeing surface mount parts many were "Oh no! we can't solder those!" ( Fine tip irons and more flux ), when we moved to ever smaller parts (01005) "Oh no, we can't see those properly" (Microscopes), when we moved to BGA "Oh no, impossible to solder those" (Stencils and solder paste), and so on.
Yes, Apple makes it troublesome in many ways but for all the areas/options they close off, there's still a lot of repairable devices and areas on their devices.
I do, like most people, wish that Apple would cease with these excessive moves masked as security improvements but it is what we have and you can either choose to cry and close up, or you can be realistic and see that there's still a lot of work available and simply redirect today's clients back to Apple until a work-around/solution becomes available. Still repairing iPhone 4 and 2010 Macbooks here, so there's a long life in these products and a lot of work.
