Personally I agree and usually prefer more "unix like" applications like this.
However from a support point of view there is value in everyone running the same consistent program rather than several hundred mini programs piped together in some way.
It also makes purchasing easier, for example you can just buy photoshop/illustrator/whatever and have all the features you need straight up rather than having to choose between programs for different actions (say one program for drawing vectors , another for applying filter effects, another for format conversion etc etc).
