Those are just people who expect things for free. Free loaders will always exist and they will always try to come up with justifications for why their free loading is actually noble and not just selfish.
They are providing a service to the people protecting their services with recaptcha and you're solving those issues because you value what's on the other side so no I wouldn't consider that free loading.
Some people just really like to believe and repeat anything a corporation tells them. It's so much easier than forming your own unique thoughts. Buy coke!
If the "price" to load a webpage were that you run a crypto miner or give a site access to upload whatever files it feels from your computer, would you do it? Or would blocking such malware make you a free loader?
