Actually many of them regularly donate to charity and have employee charity matching programmes (https://macrumors.zendesk.com/hc/en-us/articles/202084918-Ap...)

I'm not sure if only money would help in this case without tackling the fundamental reasons of why people are homeless (lack of social security and affordable housing). California is the state with the highest income taxes but little goes to solve these fundamental problems.

Pointing to companies and claiming "you make money, you should fix everything that goes wrong here" is too simple in my opinion. Companies exist to create wealth for the shareholders. I don't particularly like it but that's how the system is set up.
