Thank you for that. And thank you for your contributions. My point about the store was more aesthetic. If you are ideological about the openness of your tool chain (and I start edging that way the closer things get to science), then the "exit through the gift shop" is mildly off-putting. I say mildly, because it still doesn't prevent me from recommending it over other alternatives. I also understand that your paid products add value (and in the case of MKL, aren't yours to open-sourcify anyway).
The non-store link definitely feels more open-sourcey. I'll be sure to send people that way. Again, I didn't want to imply that you all were bad open source stewards.
