Some type of logical fallacy in the line of reasoning connecting your "quoted" text to the op.

Exploit (Oxford def.): "make full use of and derive benefit from (a resource)." Contractor (Oxford def.): "a person or company that undertakes a contract to provide materials or labor to perform a service or do a job"

Did Apple mislead these people into thinking their contracts were indefinite or not potentially bound by some end date? Did Apple retract guaranteed equity in the company?

This is literally what the contractor market is for: provide resources in increasing and decreasing amount due to market demands.

I certainly sympathize for the long tenured full time tech employees getting laid off. I really sympathize with the fact that contractors tend to be non-native or immigrant demographics, or out-sourced to other countries. Maybe that's what you were talking about, but seems like an intentionally generaliezd critique of the contracting industry.
