Hmm never had a typo corrected with a limerick before, thanks Chris Mortika for the mild amusement.

Anyway, so there were alot more threads about this then I was aware of, hehe. I guess the whole paladin of the lawful evil god would be a hot button issue. I am definately far more layed back about this sort of stuff because even as an AP subscriber, the material is most of the time more for inspiration and ideas then to be used as canon. There is still only one publisher that gets a blanket ok at my table, and that is Super Genius Games. But that is mostly because they produce self contained easily digestible (small) products instead of the massive interrelated libraries of stuff the big publishers put out. Bigger the scale, the better the chance there is of something being in there that's out of wack. It is litereally inevitable.

I will have to re-read the article itself, but it seemed to me to be an article to help dms write interesting storylines for their game and not something to be used to justify characters. But then again, like I said I am extremely willing to handwave great swaths of material into and out of my game(always with proper notice to my players of course) so it just doesnt seem to be a big deal to me.

But anyway, back to the main point from the OP's thread:

Does the PDF still have this section?

It is extremely unlikely the PDF will be edited in the near future if ever. I dont have access to my copy of the pdf can someone check? But i would be 98% sure its still there.

- Is the book receiving errata?

Same as above.

- Will the PDF be adjusted to remove this section?

Ditto.

- What other sections of what other books should I disregard?

Honestly, any and all that dont work for your game. If you are talking about organized play, there is a list in the pathfinder society guide of what is legal from non-core products and what isnt. I am pretty sure that this particular article from CoT is not in the list.

- If I can't trust the printed material that I purchase to be canon, then what reason do I have for purchasing the printed material?

To improve your game. No game material will be perfect. You wont like everything that is ever put out by any company. Buy material that has things that inspire your imagination, your group members, and yourself to envision amazing characters doing awesome things. No publisher will ever be perfect, if that is what you are looking for you will never find it. Paizo however is better then most in my opinion.

- If the PDF is not being re-edited to take out the section that should never have seen print, then why not? Why buy the PDF?

Not everyone buys the print copy, the pdf is a cheaper, more portable version of the product. That said when a product is corrected (like the Core Rules for instance) the pdf is also edited. Its just unlikely that an adventure path will get that treatment.

- If the rules as printed don't tell me enough to be able to know whether my character is legal or not for PFS play, then do I just show up and hope for the best?

This goes back to my previous response, there is a list of what is or isnt legal in PFS in the guide. This is updated regularly. Check it before going to a game.

- Is this an isolated event or should I expect to see a lot of this and just get used to it?

There have been other changes, such as the change to the paladin's smite, but in terms of scale they are less frequent then any other major game system I have used in the past.

- What steps are or will be put in place to avoid this happening in the future? Or should I expect that how the setting works will be different depending on who is saying what in any particular thread?

I would say there are lots of things in place already. Like i said, with something as big as the body of work paizo is putting out, problems like this are literally inevitable. To much written, to many different people doing it, not enough time to cross check everything. The article was meant as a cool tool to inspire dms and has apparently lead to a fire of controversy I completely missed when it came out. In the end like I said paizo is definately more layed back about 'the word of law' tnen wizards or most major companies are. I am quite certain that attitude extends to most organized play tables. I really doubt even if you showed up with a cheliax aligned paladin who has this weird fascination with asmodeus you will be turned away from a society table. Though I do anticipate some serious difficulty attaining the faction's goals for many scenarios. But that is an entirely different story.
