Heh, I was confused as well. Looking at the original source of the blog post from Positech, it looks like it's actually about why the dev isn't continuing to work on more post-release support for Gratuitous Space Battles 2.
I agree, was fun at first, but rapidly became a grind of epic proportions. Also grouping with friends is an issue due to only having one character and there being no sort of bolster/mentor etc mechanic in effect. So unless you play together 100% of the time you will be at different power levels.
I read somewhere that some of the co-op missions can be played on free accounts. Not sure how many etc, but may be worth checking out
