As I am not Google, I cannot answer that. Perhaps it's because they only acquired reCAPTCHA more recently and haven't switched over systems, or maybe it's because they feel it too complicated to use for users, or maybe, it's just as you say, it sucks too much for them.
However, if it really is so bad, then why would everyone use it in the first place?

No, but I expect any captcha type service to do exactly the same, not just Google.
In fact, your entire business model lies on the effectiveness of your captcha system, whereas this isn't the case for Google. If you want to view this issue from this perspective, I think it would be the small services which would most likely not admit flawness of one's system.
