Could you explain what you mean by "unprofessional" here? Personally Google's business model seems to be the unprofessional thing in this conversation.
It's unprofessional by definition because it is so clear that the person responding does not consider this their profession.
Their goal is not to satisfy everyone who comes to their mailing list, that would be insanity.
Instead of considering it in a balanced way and producing a polite & considered response, the response was idealistic rhetoric. For better or worse, I think that does qualify the attitude of response as "unprofessional", as stingraycharles pointed out.
As a non-native english speaker it is quite difficult to find an enough but not too much snippy/snarky response (had e.g. to lookup these words)).
English is a second language to me, and I cannot imagine this being true.
On another note - does chrome/chromium build on freebsd? Is there an equivalent api there?
I certainly sympathize with the chrome/chormium team: they're of course free to abandon users on old kernels/os'. It is a bit odd to demand a new kernel (newer than most Android installs uses) for a browser. We've come to learn to live with not having stable and secure browsers (choose either - usually choosing the updated, secure browser makes more sense). It's a bit more hairy when you need a new kernel. But I suppose newer hardware can just run Chrome (or chrome os) in a kvm vm anyway...
