To generalize, the title can be "What It’s Like to Work Inside Company X's subcontractor."
Similar stories about subcontractors with less benefits & perks were written for Microsoft, Google, Amazon. Subcontractors are always going to be "2nd class citizens" compared to real employees of the client company. The phenomenon is not specific to the tech industry. Even a workers cooperative like Mondgragon outsources work to subcontractors and those non-employees complain about not being able to participate in Mondragon's benefits.
The "subcontractors" that have the same level (or higher level) of prestige and respect as the client company would be consulting companies like McKinsey or Bain.
