Over the last few months Magisk project became very popular. By adding this modification to our phone we can easily receive root on our device, and additionally this modification allows for installing other useful modules to our phones or for hiding root from some apps which theoretically can't work on smartphones with root (including Google Pay or Pokemon GO). As we can deduce by decisions of Huawei, bosses of this company won't allow for such an easy rooting of smartphones and they want to forbid Magisk on smartphones produced by Huawei.
One of Magisk developers published on his Twitter account information that the newest update of system for smartphones produced by Huawei won't allow for booting of device after detection of Magisk modification. If this information will be confirmed, then the development team of the Magisk project will abandon developing of their program for Huawei phones. Reaction of people on the Internet was very fast - many clients stated that if Huawei won't allow for installing Magisk on phone, then they won't decide for buying Huawei's smartphones in future.
