Thank you so much for this post. I am a person who is not used to ever asking for my money back. But I felt these banner ads were misleading and to be honest I felt cheated. I made the request and gave a link to the mailing list post and quoted a couple of lines from it in particular. I am grateful you were there to help me practice being assertive.
Imagine my surprise when I clicked your profile and saw the first word. That, combined with the quotes found in the post’s URL and the fact that it was posted in the first place lead me to believe the issue likely lies with the Wikimedia Foundation. I will continue to use Wikipedia as before and due to you taking the time to reply to me I will hold it in the same high regard.
