How up-to-date is the list of organizations that support?

[ablzh]

On the page "About the Ruby Website", there's a list of "Also many thanks to the organizations that support us".
I saw that IBM doesn't have a logo, so I decided to add one, like other organizations, but I wondered if the list was up-to-date.

Is this an up-to-date list of organizations?
And if the entire list is up-to-date, which logo should I use for IBM?

Is this an up-to-date list of organizations?

Yes.

I discovered that we needed to sign a legal agreement to use the IBM logo, so I left it out when creating the page, and I don't plan on spending time on it in the future.
