I'm familiar with companies automating access to software only accessible via the web with poor/no API support. This is software they pay (usually a lot of money) for, and usually has built in captchas to guard logins. They aren't a large enough customer to ask the removal of these captchas or whitelabelled (just one out of many SaaS tenants), so they simply work around that restriction.
