At around the time non-existent 5g conspiracy theorists were being mocked constantly, was also around the time the UK was going to be letting Huaweii install 5g infrastructure. The US then pressured them not to because we're not going to let China intercept our intelligence that we share with the UK.

I think mocking the 5g conspiracy theorists (who don't even seem to exist) was to make anyone criticizing Huawei seem crazy.
