no seriously - as i once created an english wikipedia article more or less for fun i know a thing or two about how to get it accepted.
Keep it short - only the most important info. you can add everything else once it is officially in. NOT before. And everyone of the sentences should have a good reference. Not whole paragraphs.
Keep references as relevant as possible. Meaning: i am pretty sure your references are made for the dumpster. Who the fuck is haseke, who is plikat? Go for the big names probably everyone has heard before - preferably with an own wiki article you can link in the references. e.g. I found a c’t article and one by Die Welt mentioning delta with a short search (didnt check the article themselves. But i think you know what i mean. Like in the first tip: you always can extend later.
Before you submit the draft. Try to get a wikipedia admin in the live chat. I tried submitting mine a few times “normally” before i asked something in chat. The live discussion with a wiki admin there - where i could explain and tell about the relevance (which basically is: mentioned by some big shots, some official price or similar) finally got mine accepted.
Not to sound harsh - but in my opinion
every linked refences in your draft is … shit .
For now no one cares about what may or may not happen with mozilla.
Function section has no reference
availabilty is irrelevant for the wikipedia (compare to other apps)
security has a long paragraph with one reference which is not relevant
So again: basing on what i experienced it has to be much shorter, the references have to be much better.
For now you only want it be be accepted. You can add crap later
