At least currently, AirDroid is a FAR greater threat to global security than TikTok is.
Regarding security, your claims are unfounded. AirDroid has published official statements outlining a pretty robust setup for security and privacy. They explicitly talk about using end-to-end encryption for remote access, HTTPS/SSL for data transfer, and they clearly state they don't sell user data. They also specify that access to your device is only based on the permissions you grant.
I could only see it like that, I'm sure that the reason of this banning if you can see is that Trump and US administration is just like a thug that were hired by some company to hinder/destroy the rising company.

But AirDroid gives you full remote access to your Android device through a web browser. Including messages (reading/sending/receiving), camera (taking photos/videos, and accessing existing photos/videos), and full access to files. It's used widely (even by corporate IT) to transfer files between Android devices and PCs over Wi-Fi.
It's a very functional app with remote access to millions of devices, and just like Huawei there are of course a steady stream of major security vulnerabilities. These may be plausible-deniable "bugdoors", or just sloppy practices introducing major vulnerabilities than happen to be exploitable by independent researchers and nation states.
The issue is that it's developed by a company based in China and thus very closely linked with the Chinese Communist Party and given what we know about the CCP, it's almost certainly regularly being used by the Ministry of State Security and People's Liberation Army for to exfiltrate specific highly valuable files eg, private messages, VPN and SSH keys.
It seems strange there's no debate on banning AirDroid when it poses a far greater immediate threat than TikTok.
