I dislike the widespread use of captcha regardless of provider.
I realize anything connected to the internet will be subject to automated abuse, and it's impossible to run some types of services without taking some steps to defend against it, but it seems to me there's usually a way to handle that without invading the user's privacy or wasting their time. The exact details will vary based on the type of service, of course.
One particularly egregious misuse of captcha in a service I use presents one after I enter a correct username and password. An incorrect login says so without presenting a captcha. The potential reward for an attacker who successfully gains access to an account is high, so it seems almost certain anyone running a targeted attack would defeat this by handing it off to a human upon detecting that they had a good account.
