Its turning in to the new version of "3rd world outsourced phone support" A strong indicator the user simply doesn't care about the customer experience.
For some industries / companies, this is perfectly OK and BAU. For others it can be a company-killer.
I see a captcha and I know the company doesn't like me, doesn't like what I'm doing, and doesn't care if I know how they feel about me. And for some situations that's perfectly OK. Certainly not all.
