> made the business decision

IF they made the decision. There is more and more people there who doesn't even understand the concept of a website.

To them 'being on the Internet' equals being on Facebook/Instagram.

It is hard to make a decision about something you don't even know.

while i would give these businesses the benefit of the doubt, i would also say that the responsibility is on them to know. Ignorance isn't a real defense imho.

It's true that making an independent site to host your updates and info isn't as easy as just posting to facebook/twitter. I understand why a lot of businesses, esp. small ones, don't bother. Each rain drop also don't hold themselves responsible for the flood.

There are some kind of Facebook settings that will let people access your page with only a frequent pop-up telling you to log in. The "extra mile" is enabling that rather than leaving on whatever setting requires someone to be logged in to see your page.

I'd still be annoyed I have to use Facebook, but it wouldn't impact my decision to visit the store. I'm not going to a store when I can't tell if it's open.

"Made a business decision" is not the same as "it's ok", and it's dangerous to conflate these. I'm not sure where posting on Facebook falls, but for a relatively clear-cut case consider "made a business decision to not bother with wheelchair accessibility".

There are laws preventing you from ignoring wheelchair accessibility. As a society we have decided it is important. We’ve done no such thing for keeping information on Facebook only.

That's not a counterargument since maybe we should.

We have those laws because we had already decided that was a Not Ok business decision. That was true before the laws came into effect, and would hold even if we didn't manage to pass the laws at all. Moreover passing laws is not the only way to express a shared moral judgment. Anyway, I was very explicit about it not being exactly the same situation.
