The user thinks:
Gee, I did all that typing thinking I was helping Wikipedia.
It's just like I designed a neat logo for a charity only to find it thrown in the trash by them and then snapped up by McDonalds.
Yes, it's nice to see the logo get used, and yes I have no regrets putting a GNU copyright on it.
However, I thought I was helping the charity, otherwise I wouldn't have made the effort.
So I will think twice about helping that charity next time.

Indeed that is what they want him to do, think twice: only submit the best of articles to Wikipedia.
And if that gets deleted too, then think thrice.
