If you think there's a legal issue, this, obviously, isn't the forum.
If you want to tell people "I had this idea first!" this also isn't the forum; you're either wrong, or are pointing to the wrong thing (patents aren't particular readable or understandable); show us the thing you made.
As it is, it's not clear what your intent is (hence my question). You aren't congratulating them. You aren't expressing excitement. To your credit, you also aren't claiming they're infringing, though it begins to approach it.
This is a good forum for it since it is for showing new products.
If this violates a patent, I definitely want to know.
If it doesn't, then there will be no problem, right?
If not yes to all of those, the comment hasn't helped illuminate you in any way.
