A good starting point for people coming into the industry is usually tech support (L1). Maybe you can find a position in a company where they use many FOSS applications (they are quite widespread). From there you can specialize yourself and transition into a system admin.
But keep in mind that “breaking the power of tech gigants” will most likely not pay well (unfortunately).
Edit: depending on your degree you might also fullfill the criteria for graduate training programs. They will usually put you in a higher ranking position in a shorter period of time.

I also discovered this some days ago and was quite disappointed. One thing is committing the crime, but why would you “brag” about it years later in an autobiography?
Does anyone know if there can still be legal consequences for this?
