I think Alex has every right to complain.
Alex's insight into the learning process is incredibly interesting, and comes from his personal experience and studying. This means a couple things:
1) Intending to say that someone else's work is your own is plagiarism. This includes paraphrasing their ideas without proper credit. If someone plagiarized me, I would be upset, AND I would have a right to complain.
2) If Alex had the intention of communicating his ideas or articles to the forum, and didn't because someone else posted it as their own work, then we, the audience, are getting second rate, filtered information from a second source, rather than a clear and well-structured article from the true creator. This means that Alex's intentions of HELPING an audience are diminished because someone else wants to appear knowledgable.
3) The biggest one of all: If Alex is compiling this information in the hopes of creating a study guide or a book that would enter the market as a learning resource, and DIDN'T want it posted on the forum because he wished to market this resource, then someone is destroying a tangible financial asset that belongs to Alex.
Chang Liu, nothing personal, but if this is true (and I don't see why Alex would lie), then just stop doing it.
Alex, no credibility lost in my eyes either, despite what LongTimeReader may believe.
