Now that I got your attention with the catchy title, lemme rephrase that in a somewhat longer sentence:
Google is the greatest danger to the Free Software movement at the current time.
The first problem I have with Google is that they are actively working on making the world of Free Software a worse place. The best example for this is Native Client. It’s essentially a tool that allows building web pages without submitting anything even resembling source code to the client. And thereby it’s killing the “View Source” option. (You could easily build such a tool as Free Software if instead of transmitting the binary, you’d transmit the source code. Compare HTML with Flash here.)
The second problem I have with Google is that what they do actively confuses people about Free Software. Google likes to portray itself as an Open Source company and managed to accumulate a lot of geek cred that way (compared to Apple, Amazon or Microsoft). But unfortunately, a lot of people get introduced to Open Source and Free Software via Google. And withholding source code for a while, shipping source code to something similar are close enough to confuse unsuspecting bystanders. And I fear that behavior is doing more harm than good to Free Software.
All that said, I don’t think Google is stupid, illegal or even illogical in what they do. Everything they do makes sense. All I’m saying is that they’re scumbags and you should be aware of that.
