I think the point is, it seems extremely unprofessional for you to use your company newschoolers account to publicly bash other companies in your industry.
It is okay to compare a product to another product and say you get more for your money with one product over the other or highlight the benefits of your product compared to another...
but it is not okay to use derogatory language (even if it is not profane) to degrade the products of another company. Sure, you can do it (you just did), but it shows how little respect you have for this industry as a whole.
I am okay with your products, like many of them, but your unprofessionalism (not only here, but elsewhere as well) makes it unlikely that I will ever buy your product. Sure, I likely won't buy adidas either, but I think its time you grow up a little bit.
