Yes. The "profits" part is not really relevant (the same provisions also apply if you distribute squid for free). What's relevant is if you distribute squid in any way or form. In that case you need to distribute (or offer to distribute at a nominal fee) the source code for squid, including any code you added to it yourself (due to the wording of the GPL, authentication and authorization helpers are not covered and so the offer need not apply to them, but static and dynamic libraries are covered) -- /kinkie
