The way I read this article in English, were the original article still online, or had it been archived by archive.org and the Wikipedia link changed, then it could stay up. Does that make sense? The article doesn't link to German coverage so it's hard to learn about the underlying matter.
Well, it depends. The EU doesn't like free speech; archive.org is not exempt (April 10th): https://www.techdirt.com/articles/20190410/14580641973/eu-te...
Presumably, if China asked Wikipedia to remove something, Wikipedia would say no, regardless fo whether doing so violates Chinese law... right? What makes China different from the EU?
This question applies to GDPR as well.
