At risk of making points for the other side, AI Welfare Debate Week is something GLaDOS would come up with as a ploy for more bodies to experiment with.
Welcome to the Aperture Science AI Welfare Debate Week! [confetti]
Are you a self-proclaimed smart person? Do you need to share your shower -- [sarcastically] thoughts -- with the world? Do you struggle to make friends with other non-robotic entities? Our facilities are an ideal place for an -- [pause] exceptional -- member of society as yourself.
In our open and legally nonliable environment you will be able to discuss and share all of your ideas, fears, delusions, and otherwise intrusive thoughts with a wide range of AI cores, objects, turrets, failed experiments, and/or garbage compactors. Here you can freely throw spaghetti at the wall and see what sticks. (Please do not actually throw spaghetti at our walls. The portal-conductive surfaces emit deadly neurotoxin when in contact with tomato sauce. I always wondered who designed them that way. Oh well.).
Doubt that is needed. GLaDOS could just label the doors 'deadly experiments run by AGI' and enough of them would rationalize themselves into it being some sort of 4d chess move pulled to hide the actual safe room of things the AGI doesn't want you to discover and walk in.
If GLaDOS includes a small typo on the door it would convince even more of them.
