Well I don't know about ridiculously cheap, but I do think it's reasonable. That's not the point.
The point is that GP posted a free, offline first, cross-platform, good looking tool and OP commented saying 'well, this isn't what I'm looking for' like HN is their own personal wishlist, and then eventually finds what they're looking for, and it's not free, it's not cross-platform.
HN is not my own personal wishlist. However, it is often how I discover new and interesting things. As a result, whenever someone posts a link to a new tool or service, I tend to react to it with a personal evaluation. I rarely post a comment with my reaction; usually, it's to make a critique about a particular feature, design element, or bug that I notice.
In this case, my original comment was too succinct to be useful to anyone else, which I believe is your point. Correct me if I'm wrong on that.
Fair summary - I think perhaps a few of us just felt that the comment was a bit abrasive given the time and effort that's clearly gone into this which is being offered for free.
It looks like you see and acknowledge that opinion, which is nice, and fairly uncommon on the Internet still :)
Hope you have a good weekend and a wonderful Christmas - and it's good you found a tool that does fit your needs in the end!
