I think IT services (e.g. administration, support) and software development are effectively separate industries as concerned for labor organization. Business has clumped the two occupations into a single general category, but the reasons are in service to their own interests.
Software developers recently have not shown broad class solidarity or class consciousness.
Of course, some do exhibit such traits, and some have managed to find each other and to create pockets of organization and resistance.
Largely, however, the current generation of the occupation has been captured under the trance of techno-utopian ideals, as embodied in Silicon Valley, if not the more classically liberal ideals of Wall Street, and has been too comprehensively enclosed in its own bubbles to reveal any notice or concern that the systems operating from such ideals have been immense failures for the mass of the population.
