Congratulations!

(I'm an ebook reader, not much of a comics reader.) It doesn't bother me personally, just because I disinfect the moment an ebook hits my computer, and I run automatic offsite backups of my Calibre library. But I realise not everyone knows how to do all this, and they shouldn't have to. I reckon if you sell ebooks with DRM and a re-download capability, you should maintain the service you've sold, not drop it with a couple of weeks' notice.
