I think this is a false comparison. What do you think happens to the cockroach after the experiment? It is set out to freedom?
The real comparison is killing something living vs. torturing something living and then killing it.
Additionally, I think it's arrogant to think that humans have rights to torture animals (needlessly). Of course, it's a whole different debate whether we have the right to torture animals to save humans (drug testing etc.).
Wow, your logic is quite bad. Pay what you want is charity, you say? I respectfully disagree. You think of tipping as charity? That's interesting.
Further, your "penguin power" argument does not hold water since in the World of Goo sale the devs initially did not tell the buyers (yes, buyers, not donors) that they are tracking the sales by operating system. Granted, once they published the distribution the gap became a little bit bigger, but not significantly. My interpretation of this is that after seeing that they pay more on average, the Linux users were even more eager to show that they are a market segment worth looking at.
So, you don't like my stats. Where's yours? Oh yeah, I forgot you're just talking out of your ass...
The Humble Bundle statistics are not the only source that points to the direction that Linux users are more eager to pay for quality software. I seem to recall that the people behind World of Goo released similar statistics. Yes, here they are. One factor might be that Linux users might have more buying power than average Windows users. This has probably been researched somewhere. Actually, it's easy to argue quite the opposite what you're saying: Since the Linux software market is not yet that mature, it's easier to attract new customers for your product.
So, respectfully Sir, I think your argument is full of shit.
This is the first year that I've been completely Windows-free, and that's basically for two (or three) reasons:
1) Pro audio workstation software is finally coming to Linux
Tracktion published a Linux beta a while ago, and later this year (hopefully) Bitwig Studio will be published, also on Linux. After this one, the rest of the developers will follow up. While waiting for these, I've been using Reaper, which has an officially supported Wine build.
2) Pro video editing software is finally coming to Linux
In April, a public beta of Lightworks was released for Linux.
3) Gaming
Steam + the Humble Bundles. Suddenly, there's an abundance of Linux ports of great games. Other developers will follow.
So, 2013 is, finally, the year of the Linux desktop, but perhaps not in the way it was expected to happen. The OS field is more fragmented than ever. But perhaps it doesn't matter. It is also easier to port software across OSs than ever. Or at least design your software for portability.
It is not every question that deserves an answer. -- Publilius Syrus
