Right, but if those tricks are legal, they can be pre-loaded by Huawei. If they are NOT then likely the average people will not be able to do them, although the techie community can. The Chinese government can also hire people to anonymously load up and spread on the internet easily-found sources for how to do make your Huawei use Google stuff for people who are in between the techie and average Joe group.
The end result is the same; it's just to see how much global market Huawei can hold onto while it develops its completely indigenous alternative. And even if it's none, the end result is the same again, use proceeds from the Chinese market and support from the Chinese government to develop indigenous software and then promote and re-expand. That second phase won't be fast because a lot of people are used to Google, but once this second phase takes off, it's the final journey, never looking back and never allowing US hardware or software into Huawei (or Chinese) phones again as they dominate the world market.
