The pro-CCP crowd all over Reddit has been saying it for years. The typical arguments are that there is zero evidence and the US is being anti-competitive and discriminatory.
Both things can be true and it doesn't have anything to do with being pro-anything.
The US government has a very long history of simply lying about things when it fits their goals so independently verifiable evidence is what's needed. The German government is still waiting for the promised proof about Huawei backdoors, by the way. This was promised when Trump was president. The US didn't produce any proof whatsoever and leaks even showed that the NSA couldn't find anything even after gaining access to Huawei's systems. The UK also said that the US never produced any evidence for any of the claims.
Now it might still be true that there's things going on but there's a huge difference between saying "We don't have proof but we obviously cannot be sure" and claiming to have proof.
