Google was forced to cancel Huawei’s licenses when the United States government mentioned the smartphone company as one of the companies that US companies are banned from doing business with.
The cancellation of Huawei’s license is a big blow for the smartphone company as this will affect their market in European, African, Asian countries, and North America as well.
The US government is of the opinion that Huawei has some ties with the Chinese state, and such a tie can allow China to spy on America through backdoors that can be built into the Huawei products.
Although no evidence of such a possibility has been confirmed, the US government has banned US companies from doing business with Huawei. Therefore, Google has no choice but to obey the rule.
