Because the manufacturer and seller are in China and they want to make an example out of someone?

Yeah, it's weird bcs as I understand that copyright law from 1941 is for the actual distribution, and if he never got paid by anyone in the distribution chain (tho as understand he did get some free consoles to review), then he wasn't part of it - just filming himself saying what can be bought on the market.

Almost certainly there was some kind of pressure by somebody well connected on some higher up in the Italian Justice or Political Authorities of the

"Something Must Be Done!"

"This is Something we can do"

"We shall do This!"

It's pretty standard in the stuff which isn't their daily bread and butter that Justice Systems are driven by cronyism at the higher level and cover-my-ass at the lower level, especially in countries which have a culture of Cronyism.

(People are people, and even in Justice Systems they're no more impeccably honest and fair than elsewhere - in fact positions with power tend to attract people who are less honest and fair than average, IMHO).

Often this shit gets overturned when it gets to court or on at least appeal (generally the system gets less crooked as you go up, though I know of cases in other similar countries in Europe were only when it got the European Court Of Human Rights was the injustice corrected) and once the Press' (and the higher up's) attention has moved on, but that is a mentally and economically very costly fight for individuals to fight, which is why poor people almost invariably get shafted in such a system when they cross the wrong person or "don't know their place".

why target the youtuber though?

It's the same taking the fight against drug dealers to the drug users. They don't care about the lives they ruin as long as they can punish people.
