2. Obviously mostly yes, but in hn people just assume that you're a somewhat good person who wouldn't knowingly restraint internet access to people with disabilities

If you are making web sites for public use, the law disagrees with you.

Of course that's up for the developer to decide. You can't force a developer to make a website accessible to all people regarding of their capabilities.

But you have to remember the initial goal of why the Internet started as open and what was the initial goal, to make all information accessible to everyone, that's why accessibility standards were there since the beginning.

That was the entire goal of the web, to be open and accessible to EVERYONE.

But if you want to go full head on capitalism and argue it doesn't matter for business, accessibility is literally search engine optimization, which is great for business. Googlebot is blind and doesn't use a mouse to surf the web.

From any perspective Accessibility is a requirements for any website or web application. Of course, nobody can force developers to make websites accessible.

Wait, yeah they can:

No - in most western countries it's decided in law that reasonable efforts should be made to support most people, those with disabilities like visual impairment included.
