How is that an excuse? It's like having a café that only lets people wearing t-shirts in. Are you wearing a sweatshirt? "Well i'm sure you can download a t-shirt for free from your cupboard or one of your friends" /s.
It's a fundamental principle of interoperability ("strict about what you offer, lax about what you accept") that an online service should try to serve anyone, whether they have this or that technology or not enabled. In the case of the web, anyone with HTML parsing technology should be able to browse it... minus some stuff that actually doesn't work without additional technology.

I wouldn't know, it never let me through. I have to say, as a sighted person, the only times i've tried audio CAPTCHA were when Google wouldn't let me through using visual CAPTCHA (infinite CAPTCHA loop). Not even once have i been able to pass it.
I guess once you're on Google's no-pass list, whether you fill the CAPTCHA via audio or video doesn't matter, they're just not letting you through? I find it worrying that some people accept to have a private corporation strip-search their guests on the way to the doorbell/mailbox.
