Nothing deeper, skeptical is a fair term but impractical.

Consider instead what the person stands to gain.

In my case I invest in my network because it makes me independent and that is my objective and I am happy to pay for that.

For other people its because they might want to foster open source (freenode for example) and thus your for-profit business or gamer clan isn't the right fit.

Due diligence is the correct term. Not skepticism.
