I read in a book some years ago how some Sorbian speakers had started to use articles under the influence of German, but I've no idea how widespread it was, and I think it's been discouraged during language revival.

When Wikipedia says "Sorbian uses no articles", it is not telling the full story.

I couldn't find much on this online when I searched for it. But did find at least one respectable reference, which agrees with what I remember:

https://www.researchgate.net/publication/277973156_Unarticul...

Abstract: "Slavonic languages in general do not use articles to indicate (in)definiteness. The development of an article in some of them is the result of language contact. In the case of Sorbian the influence of German led to the use of the demonstrative pronoun ‘this’ and the numeral ‘one’ to indicate definiteness and indefiniteness, respectively. Originally the German system was copied almost without changes, but eventually specific rules developed, subject to phonotactic constraints and restricting the use of the article mainly to intratextual and pragmatic definiteness. The use of the article depended on the kind of text and language (spoken language, Bible translation and original texts, translations from German). Grammatical purism managed to eliminate the use of the article in today’s written variants as well as in most official uses of spoken Sorbian almost completely. In colloquial language and in the dialects, however, the article is very much alive but its use differs considerably from German. There are also differences between Upper and Lower Sorbian, the latter being closer to German usage."

Wikipedia tends to be better on linguistics than some other areas, but best not to become over-reliant on it. This is just one reminder that it does not cover many things.
