I think there is a difference between guilt and complicity, though they are related.
I have somewhat limited agency in this world, limited to the little bit of money I spend, the movement of my arms and legs, the words I speak, the things I look at, and my thoughts and intentions.
Not really, in a free market consumers directing their consumption away from a sector does not make them complicit in the abuses or bankruptcy of that sector.
They don't have direct relationship to that sector anymore, after all.
Companies that use these services could exert pressure for better conditions, just like some have done with other companies in their supply chain.
