As far as the EU Cookie Directive is concerned, I don't think this is correct. The directive stipulates that you cannot use non-vital cookies until the user explicitly consents. This consent must be freely given, i.e. it must not be a requirement to use the site. Since our banner is mildly annoying but doesn't prevent use of the site, I think this complies. As a side note, I'm not sure you can be in "violation" of the ePrivacy directive, as it is a directive, not a regulation (unlike GDPR). This will change when the ePrivacy Regulation[1] comes into play. I might be wrong here though, IANAL.
However, since a lot of people are not a fan of our banner, we've decided to add an explicit "no" option. I still disagree that our original implementation is a "dark pattern", as we very explicitly[2] will not sell your data, and tracking for the sake of improving the product seems like a square deal to me. But I can understand how people would find it annoying, so it's been changed. Sorry about that.

From looking at the currency used though, it seems that you don't need to concern yourself with EU stuff soon =)
