Why those phones will be less secure and therefore easily hacked? Which kind of argument is that?
How a huawei phone with a forked android is any less secure than any 2-year old android phone from $randomanufacturer (not longer receiving any OS update at all)?
Google is trying to move Android to a more secure footing with Titan, Play Protect, verified boot, etc like ChromeOS. If Huawei becomes the dominant Android phone manufacturer, there is the possibility for things to be worse than they are today.

Huawei's drivers, which is what led GCHQ to probe into Huawei's code and write a rather uncharitable report on what their coding practices look like [1], are not. Admittedly, as members of the public we can only take their word for it that they found shoddy code by any reasonable standard. But if the latter is true and any indicator of how they'll maintain their own fork of Android, it's doesn't inspire much confidence.

Some of it. Certainly not many of the hardware drivers. There's a reason that updates are dependent on hardware vendors and mobile network operators and that most phones don't have fully functional Lineage builds.
The thing about exploits is that it only takes one. It doesn't matter if Huawei adds another one when there are already thousands to choose from.
