More posts isn't always better, it's the signal to noise ratio that's important.
I assumed he already knew about the free version of Eagle.
Often when people compare open source software to proprietary software, they say free verses non-free software, even if the non-free software can be obtained free of charge. In this case they're taking about the freedom to modify the software, see how it works and re-distribute it, not just the price. For example the Fedora Linux distribution has both free and non-free package repositories which can be both used free of charge, the free packages are just compatible with the GPL and the non-free ones aren't.
If he were comparing LTSpice to some payware such as Altium Designer then I probably wouldn't have said anything because it would be obvious.
Just about every piece of payware has a free version these days and in nearly all cases it's restricted in some way i.e. you can use if for up to 30 days, it can only simulate circuits with up to 30 components, the maximum board size is 150mm squared, you can't print the design, etc. In this case I'd be very wary of calling it freeware, unless the restrictions aren't too prohibitive, I prefer the term demo or free trial. And don't forget that even if you downloaded it for free, the licence might stop you from copying it; software developers like doing this because it means they are still in control of distributing there software. I've heard of all too many people getting in trouble for piracy by hosting so-called freeware on their sites.
