I'd argue harmless, small and transparent dependencies are the easiest to avoid. The extreme of it "is_even", but any library that could fit in 200 lines should probably be owned code.
Where the article hits is critical libraries that you heavily rely on and that your code is slowly formatted around. I'm thinking specific data parsers, fancy query brokers, time management libraries etc.
