I would argue that everyone is privileged enough to make that choice. Who are these people whose only choice is FB or starve? Surely in this field anyone who can get hired there can get hired elsewhere.

I'm not saying they'll starve, but I'm giving up nothing by avoiding adtech.

That's not true for everyone. They may not starve, but they may make much less or give up the resume boost.

I love the spirit of this comment: Facebook employees as poor pawns to be pitied.

I share the sentiment as a corporate family-oriented programmer from a flyover state that has been heavily recruited by FANNGs. I don't like working for anyone, and being a teensy cog being ground up in a duct-taped together machine like that seems like torture.

You seem to have misunderstood the spirit of the comment and then projected your own notions onto it.
