It's made in different context.
One is a print of a painting (the quality of which I am not going to comment on, as it is subjective) made by a single unknown artist. The other is an advertising system that includes many high ranked and trusted members of the forum, and guarantees 1,400 new posts featuring an advertisement and >200k impressions.
Without even mentioning whether the price of each is fair (one is significantly fairer than the other), you have to understand that the things you are commenting on are very different to one another.
Lauda's comment is a bit forward, however if the OP wanted to avoid that he should have made the thread self-moderated (as Lauda did with ACE's). If that were the case, and Lauda's criticism were removed it would be absolutely fine (just like it is in this case).
