Gratipay code hosting currently fails GNU Ethical Repository Criteria Evaluations

[ghost]

Please could Gratipay migrate its entire code-base and bug tracker to a code hosting and bug-tracking service that does not fail the GNU Ethical Repository Criteria Evaluations?

GitLab is probably a reasonable compromise:

• it passes (albeit imperfectly) the GNU Ethical Repository Criteria;
• it supports Git as a first-class DVCS;
• its interface is quite similar to GitHub's;
• it has a large and active user base.

Other possible hosts, albeit lacking some of those features, so probably not currently a great fit for Gratipay:

• NotABug
• GNU Savannah

Thanks!
