He answered "no" to the "have you travelled anywhere in the last 14 days" question, I can tell you many people lie about these questions and if there's no stamp in your passport it's highly unlikely to be found out, of course him being who he is there were pictures all over the internet of him in Serbia.
But even so if it wasn't for the fake pandemic 1) this question is not asked 2) he absolutely would get away with such a tiny untruth because of who he is.
And he actually did get anyway with the untruth, according to the immigration minister his visa was revoked purely because he is a health threat (lol) and his presence may foster antivax sentiment (i.e wrongthink).
This really isn't complicated.
They've clearly made an example of him. But they were within their rights to do so. Whether you think their rules are bullshit or not (I happen to agree they are), they are the rules and it's not "deplorable" that they didn't make an exception for him. Why should they?
Well as I mentioned earlier they made many exceptions for celebrities.
They just don't like his views, if this was China or Russia there'd be outcry.
And it's more the circus and way it was handled that is deplorable. They let him in, revoked his visa and detained him, he won the appeal and was released a week goes by and then at the end of the working week (5pm Friday) just before the tournament starts the immigration minister revokes it again, why did he wait so long?
Also the immigration minister abused his power, while it is within his authority to revoke visas that power is usually only reserved for terrorists or criminals.
