I just wanted to be kind, sincere, and asked his permission explicitly in my comment I presume. At least it was my intention.

If he wanted me to remove it, I would have happily done so.

Also, I just pasted his nick to Google and it came on top. So I presume he didn’t try to hide his name. If I have sensed the contrary, I would not dig one step further.

"Asking for permission", while simultaneously doing the thing you're asking permission for, without waiting for a response, is not actually asking for permission.
