Drew makes so many great points on his blog.
"When your FOSS project chooses to use a non-free platform, you give it an official vote of confidence on behalf of your project. ... an investment in a non-free platform is also a divestment from the free alternatives."
"In short, choosing non-free platforms is an individualist, short-term investment which prioritizes your project’s apparent access to popularity over the success of the FOSS ecosystem as a whole."
