I definitely agree! I am new to quilting, and all things sewing actually, and trust the professionals I see at a quilt show, which is where I bought my pen. I thought they WERE designed specifically for fabric -- it's how the vendor sold them!
I'm glad I learned on a little piece of fabric (before quilting) and didn't mark up a whole quilt.
I just posted about this too:

I would agree, except for the fact that the manufacturer did not design these pens specifically for fabric and quilting, so why would they care? (I'm not trying to be argumentative)
My problem is with the vendors I see at quilt shows who are selling these pens specifically for quilt marking, when they haven't been created for that purpose and no one knows if they're safe. When I discovered them over a year ago, and did some research, nowhere did I read that they are acid-free and archival, which is what killed the idea for me.
