The authors basically says that it does not always like when people changes his stuff, so he thinks it's fine to do a kind of read only open source with additional unwritten rights (basically i've got the impression that it's okay to send him he likes, but he won't tell you before the rules for him to like things or not...)

He does not take into account at all that you can just modify copies of his stuff. Not his own (unless he planned to do a kind of wikipedia like repository for his code, freely modifiable by anybody without even registration).

And also: copies are naturally free in the digital age.

Also, i'm not fond the whole "i'm a good programmer, you are only allowed to look because you could be a bad one and do a mess in your own copy -- and oh I forgot: I happen to like free software, but not when I write the program" thing.
