Unfortunately, if you want to fix electronics more often than not China is the only place you can buy spare parts. I don't think buying spare parts to devices counts as "stupid shit".
In the case of the 3-EUR-tariff, nobody has come out and said "we want to make small electronics production/repair untenable", so I'm optimistically assuming its effects are not intentional.
Since then I am now getting "duty saving" adverts for them where they help you to get items on sale & in the same category. So it took them like two months not to only adapt, but to use the fee as apart of their marketing. ;-)
I was really infuriated when I heard that it was mainly the big chains like Lidl, Aldi, Ahold that have been lobbying for this crap. They are always trying to kill the little guy.
