If you read the article:
"And the irony is, not even [Sergey Brin's] engineers get paid enough to live here."
If "SV" was perfect, it wouldn't need critical articles. It isn't so I welcome them to remind us what we should address.
These articles make it sound like homelessness is the fault of Google and Facebook. Homelessness has existed in Silicon Valley for decades and it has gotten worse because the laws prevent sufficient housing to be built.
The wrong thing about this kind of articles is how they try to link tech and social problems like they were cause and effect. It's similar to other smears like "immigrants are taking our jobs", etc.
