We Need to Talk About Docker Hub

Docker lists a phone number on their website, perhaps you can try that?

Instead of all the snide remarks I’ll offer another possible solution:

Contact sales for Docker Business, first state your interest in the business enterprise plan, maybe even make some statements about how it would benefit you, but also during the sales/discovery/demo process note the problems you’re having as a free organization and how they have to be resolved before you can move forward.

Once the sales team prods the right people to fix your problem, continue wasting their time a little more as punishment and then tell them sorry, we went with another vendor.

Heh, I seem to have stumbled into /r/UnethicalLifeProTips

...not disagreeing with the approach. :) I swear something like half of my problems in life can be boiled down to poor/absent communication. If you're going to LARP as a grown-up company, as Docker seems to be, then you need to do the work and respond to the emails. Even from the freebie customers.
