Hi abruptum,
They possibly haven’t read here: Re: Advantages And Disadvantages Of Using Captcha *
Advantages:
Distinguishes between a human and a machine
Makes online polls more legitimate
Reduces spam and viruses
Makes online shopping safer
Diminishes abuse of free email account services
Disadvantages:
Sometimes very difficult to read
Are not compatible with users with disablilities (you cannot distinguish between colors as others do)
Time-consuming to decipher
Technical difficulties with certain internet browsers (well you provided the example for that one)
May greatly enhance Artificial Intelligence
(always analyze the page with uMatrix for instance and know what to block immediately of third party content, just depending on Captcha security is relying too much on AI and that is dumbing down users and others).
