If Huawei can make a set of comparable cloud services (app store, push notifications, maps ...) that runs in the eu under eu law. Then that coupled with the high end hardware they are obviously capable of making would make a very compelling package for an European audience.
This may not be obvious to an American observer but the mistrust of American big tech is quite widespread in certain parts of Europe.

Oh, is that all they need to do? History has shown that most hardware companies are really good at writing software, so they should have this in the bag.
GMail supports SMTP an IMAP access, so they won't lack GMail. Youtube supports web access which frankly is better than the Google App because it doesn't nag you all the time. Google Maps up until recently was just another navigation app which are a dime a dozen. (For a while there it wasn't a particularly good navigation app, but they've really pick up their game recently.) I have no doubt can build replacements for them all.
But all those apps in the app store - that's a problem. Google's lead in speech recognition - that's a problem. Google pay - that's a problem, particularly as the app store is tied into it. Google's lead in image processing and cameras - that's a problem. Google's amazing ability to translate languages - that's a problem.
