Legal Question in Business Law in New York

I would need more information to give you a definitive answer however it does not appear that you've done anything illegal. The word "illegal" generally refers to criminal laws.It doesn't appear to me that you've committed a crime. then again, I am not a criminal defense attorney so you may wish to post your query under "Criminal Defense" rather than Business Law.

I think the question you are asking is, "Can someone sue me?" I don't see anything for which you could be sued. On the contrary, X, Y and Z are getting free SEO and free publicity by your mentioning them and you haven't made any defamatory or fraudulent statements which would offend X, Y and Z.

If X, Y or Z or anyone else contacts you and asks you to remove the logos, you can simply remove the logos or call an attorney to determine your rights.

Hope this was helpful.

What you propose could be attacked as misleading. Take a look at NY General Business Law Section 349 and understand why you should not do this.
