Apple has a surprise announcement planned for the morning of January 13, 2021. At the time of this writing, we know that it is not a product. Otherwise, there is no indication as to what it will be.
This leaves the possibility open for services. There has been much in the tech world recently about the security issues of FaceBook, FaceBook Messenger, and Whatsapp, which is owned by FaceBook.
Non-Apple users do not enjoy the security and all the conveniences of iMessage. I feel to bolster the security and privacy of all tech users worldwide Apple will open iMessages to Android and Windows.
There have been numerous calls in the past for Apple to open up iMessages. Apple very publicly proclaims the strength of security on Apple devices. Now would be the perfect time to let all the world enjoy the convenience and security we have with iMessage.
