"They" are Ramsus Lerdorf, the creator of PHP. The issue isn't with PHP/Apache2 per se, but with third party modules in PHP and Apache2's multi-threading. Joe can call it FUD, but if the creator of PHP says it's not to be considered production stable, I take his word over Joe's. If Joe tells me that Fedora 2 isn't production stable, I'll take his word over someone like Ramsus.
Not to mention this warning on PHP's site....
"Do not use Apache 2.0 and PHP in a production environment neither on Unix nor on Windows."

This isn't what I would call FUD, "by some members of the PHP community".
