We need a list of apps that include these libraries and any malware scanner - including Windows Defender, Play Protect and whatever Apple calls theirs - need to put infected applications into quarantine immediately. Just because it's not directly causing damage to the device running the malware is running on, that doesn't mean it's not malware.
Apps should be required to ask for permission to access specific domains. Similar to the tracking protection, Apple introduced a while ago. Not sure how this could work for browsers, but the other 99% of apps I have on my phone should work fine with just a single permitted domain.
I am waiting for Apple to enable /etc/hosts or something similar on iOS devices.
