Kann mir jemand bitte sagen was für sprachliche Mittel in den einzelnen Strophen benutzt wurden?

Well, that’s another case where you can’t see the forest in the face of trees. Instead of searching for individual language means from any checklists, you should consider the means by which you work. Then the following is really clear:
The poem plays with the word being used as the name of a product for which intense advertising is made. This is mainly due to the fact that the product name wants to thunder the readers into the brain. The third and fourth lines are particularly interesting. Because if you get out of the product name, it’s natural. But if you take the word in the sense of normal language, it sounds very contradictory. You want to have everything and at the same time give everything.
Overall, that’s a kind of parody on advertising.

Who does the poem come from?
