Why is Huawei not allowed to use Google services?

Because Huawei has been sanctioned by the US and US companies are therefore no longer allowed to work with Huawei.

Thus, as a US company, Google is no longer allowed to provide its services to Huawei.

Google is known to be a US company.

The US accuses Huawei of spying on other people using their cell phones. Since the USA does not support this, they no longer want neither the OS nor the services to be used.

But no worry. You can still watch YouTube or similar on your Huawei device.

You can still use Google with your Huawei phone, Google Maps and the like.

That was not the question.
