Yeah, I have to kind of agree here... Just because someone is considered a "hacker" doesn't mean he or she can't use someone else's product instead of building their own. Not everyone has time to build their own RSS parser and reading interface.
It's kind of like taking away a mechanic's car--they'd still be annoyed you took it away. Just because someone can build something (and maybe not quite to the extent of an entire multi-billion company's skill and attention), doesn't mean they should waste time doing so. If you think you can do better, go for it, but in most cases it's better to use what's out there.
And what is a "hacker" to begin with? I believe he meant the hacker which is defined here http://www.catb.org/esr/faqs/hacker-howto.html, and not that you should invent the wheel avoiding other products (no problem should ever have to be solved twice), on the contrary, you should fill in the gaps when it's possible (the world is full of fascinating problems waiting to be solved). That's the true hacker attitude, not whining.
