Thanks for asking.
There are two issues which bother me here. One is that I am seeing a worryingly large amount of negative feedback on this challenge, which could have easily been prevented. Instead of just presenting the challenge as a fait accompli, you might garner a lot more support by first posting what it is you are trying to do, and what your suggested approach is (e.g., by showing an Overpass query for the challenge’s source data and your assumptions about these cases). There is a lot of combined knowledge here which you can tap into, while at the same time showing that you are acting as part of the community.
The second issue, for me personally, is in how you present this challenge. Have you asked any of your Dutch speaking colleagues to look at that post and provide feedback? Whatever you are using to translate your input is generating unidiomatic — and frankly, grating — Dutch („Heb een geweldige week!” is not something you say in Dutch; it is a literal translation of “Have a great week!”). The empty motivation I quoted before just makes it sound like someone handed you a link to post without supplying you with the context for that challenge. The combined effect is a text which, to me, comes across as demeaning.
If this is caused by the translation software you are using, you might want to reconsider its use. Most of the contributors here, including those still in education, have a working level proficiency of English anyway.
Most significantly: nowhere in that post are you upfront about your and TomTom’s motivations. @CasGroenigen neatly summarized those by first stating the general purpose of the challenge (i.e., “Empty elements often represent valid map content which is lost to us due to faulty tagging.”) followed by a concrete example (“Look at this untagged line which should clearly be a navigable service-way.”) That is an excellent example of what I would have expected in your opening post.
