They should create their own instance and offer it as a service for any company with an interest in interacting with blind people.

And of course no need to multiply the logins. This would allow the blind community to focus their effort in one place without the second thought of enduring the business decision of a CEO, i n terme of design or whatever.

The fediverse is really something.
