Nothing's Carl Pei launched (broadly) iMessage for Phone 2 and bullied Tim Cook for not giving everyone the right to the messaging standard. Then everything went downhill for the founder and now also partner Sunbird.
The next day, Apple announced that it would support the advanced messaging platform RCS that Google has long hoped for, with support for high-resolution images and video.
A few days later, the provider of iMessage, Sunbird, i.e. the routing of messages from an iPhone to Android, was accused of using lousy security: we're talking plain text and using HTTP instead of HTTPS. Although people in the know rightly point out that HTTPS alone is not enough to secure personal messages or to achieve good security in general, it is a basic start.
Sunbird, the provider of message routing, which launched the messaging platform last year, reports that it is also temporarily shutting down its iMessage for Android app. The service has been in beta testing for a while, i.e. before they started the collaboration with Nothing.
