If you want a company to change their behavior, give them a reason to do so. Daniel has quite a platform being a well known maintainer, but instead of using that platform to shame the company in question, he politely emails back to the person sitting with an outdated excel sheet of 500 suppliers. That person didn't decide that the "email everyone on this list demanding info" strategy was a good idea.

To actually make a difference when you have a platform, use it. Tweet-shame them so that the fallout actually reaches the manager in question. This is just complaining about a behahavior while at the same time more or less doing everything possible to encourage that behavior.
