Going to the original topic, dunno if it was said.... but I hardly doubt a design team that has Ed Greenwood on it could be described as 'FR-hating' seeing as he invented the Realms.
It's propaganda.
And Time of Troubles did suck, imho.
I think it sucked, too; not only had my players read the novels by the time I tried to introduce it to "my" Realms (by running the official adventures), but my campaigns also suffered from losing Bane, Bhaal and Myrkul -- all of who were my favorite deities (and their followers were my favorite villains as a DM). How could I replace them with Cyric?
It's wasn't just me; Myrkul and Xvim were very popular among the DMs I know (for example, in one of the campaigns I'm playing in we're still hunting the Crown of Horns after all these years).
Then, during 2E, Xvim ascended to divinity, and I slowly grew to like him enough to introduce the Risen Godson to my then-current campaign (and I foreshadowed it in a major way). And what did they do next? Killed him, that's what they did; turned out it had been the "new" Bane (I had pictured Bane as Witch King of Angmar-ish, but now he appeared as a naked, green and bald giant...

) in disguise. So, overnight, Bane had returned... but not into my campaign. I decided to go with Cyricists, for a while, so that I could "play up" the ascension of Bane (Xvimists quickly "faded" into the background as their god struggled against his father). I began to like Cyric, too, as years went by, and thought I would never use Bane again in my Realms. And what happened next... is that Cyric is imprisoned for a 1000 years. *Sigh*. Yeah, Bane would still be a choice for me, if I chose to run 4E FR, but his "new looks" don't appeal to me (even less his new symbol, the pronged weird claw-thing).
Damn you, design team... why have you always killed/imprisoned my favorite evil deities? If you had to kill someone, why not the "Gothic Chakram Chick", i.e. oh-so-overused Shar?
On-Topic: I don't think they hate FR; they just don't have any great passions about it (IIRC none of the WoTC staff had run FR campaigns in-house for years). Ed, who certainly loves the Realms, was given a "new" corner of FR to write about, so that the fans couldn't claim he was left out; yet his work would not "jeopardize" their new goal for less details in the main areas, because it would be about a relatively distant part of the setting.
