I've reported them to [e-mail] hoping that - given enough complaints - some action is taken from their side. From my understanding I can't delete myself from their sendgrid campaign/list since they only allow to unsubscribe from all their types of newsletters, meaning my mail address (which is public in my GH commit history anyways, but that's missing the point) will stay

I'd be interested if anyone here can shed some light on whether this counts as a GDPR breach for European citizens (as myself)?

It does if you didn't consent and they use it to contact you, feel free to file a complaint
