I read this, and my first thought was "what are they supposed to do? buy houses for all these people? Yea, Apple could afford it, but then they'll be sending the message that if you want Apple to buy you a house, all you have to do is pitch a tent on their lawn".
And then it reminded me of a quote from The West Wing, after Toby uses the president's name to pull some strings for a random homeless person he happened to run into:
> President Bartlet: "Toby, if we start pulling strings like this, you don't think every homeless veteran will come out of the woodwork?"
> Toby: "I can only hope, sir."
I know that "solving" homelessness isn't really as simple as just having the wealthiest company on the planet buy homes for people, but... it could be a start.
