Maybe the paywall is a marketing move. Since their content is likely worthless, putting it behind the paywall might make it seem more valuable, and would prevent potential customers from discovering just how worthless the rest of their product are.
Alternatively, they may be putting user manuals and the help files behind the wall. Considering how buggy their products seem to be, this could be a huge source of revenue from existing customers (aka suckers).
And finally, I don't think Wally actually wrote that script. I think he simply arranged to take on the responsibility of posting all new content to the website himself. Much more efficient than programming anything.
Poor Yoshi314... he must have never heard of a paywall. For the uninformed, a paywall is something that hides content from non-registered non-paying viewers. It's a sure way to reduce eyeballs to the page and/or content. If once offered for free, viewers will reject en mass that content being put behind a paywall.
No, if they were sensible - allow the content to stay free with ads and allow registered, paying users to see the content sans ads - then people would probably be more accepting. But as soon as a paywall goes up, even for some content, people will just stop coming at all.
