You have to appreciate Mr Lewis and his posts. They are somewhat akin to a fine wine or a mature cheese - not to everyone's taste but enjoyed by a few connoisseurs
in relation to pushing products, I do see your point but will add that I personally don't think that your argument stands up for the following reasons.
The vast majority of people wishing to sell on TM are simply looking to trade to a targeted group - a sort of magicians ebay. What they are generally trading is information that they have bought, copied, learnt and then wish to pass on and recoup some or perhaps all of the money that they spend. In effect, they are learning our secrets without paying their due.
For those who are selling magic that is not information based, there is a facility to sell to the TM membership where the seller is able to relinquish the ability to perform the 'for sale' item when it is sold. This applies to all but with some buyer protection through vetting by the Mods.
Very few people here are Pro's. Those who are may have many products that they wish to sell so they have shops, web sites etc. that have links on the site. They generally sell other peoples products in a professional manner.
Mr Lewis on the other hand is selling, or promoting his OWN works which I see as being somewhat different. Inside there is a true wealth of information and experience and many could spend their money on far worse items of magic. Having been around for a few years now on TM, I also recall other pro's offering their products and I for one have been glad to see them take the time to write for (as Mr Lewis puts it) us mere mortals
Yes, his posts are sometimes condescending and tedious but you have to admit that they are also humerous (well at least I think so). Just don't take them too seriously!

It's not really an optical illusion - it just looks like one!
