They reiterated that point in an email.
We would like to clarify that Opera does not abandon iOS... We plan to keep developing it as Opera Min[i] provides unique features that other browsers do not have, such as data saving for both webpages and video, ad-blocking, built-in newsfeed etc. And people love using it. As most of the engineering resources are now on Android, our update on iOS is slow at this moment. Please bear with us and do stay tune for our next updates.
The tweet Friday also emphasized that "We will update iOS for sure."
