Could this be a scheme to sell customer data?

I assumed for some time that installing backdoors is a good way to sell customer data you otherwise wouldn't be allowed to share.

Equifax didn't fall victim to a backdoor but to an outdated Apache Struts that no one noticed.

I'm not only talking about this particular case, but in general. "Accidental" backdoors let companies share data they legally couldn't share.

Look at Facebook and how their API was surprisingly abused for years until they noticed it.
