Tales of Symphonia also suffered from 'tamed' dialouge and censorship, but of course, most of the blame goes to Nintendo's policies as well.
Those policies don't exist anymore and haven't for quite awhile, it was for some other reason like getting a T rating, fitting their perception of Nintendo's audience, or to avoid potential controversy. Just looking at Eternal Darkness, Killer7, and BMX XXX shows that the only thing Nintendo really cares about is the AO these days (and potentially the holocaust, but there's nothing concrete there yet). The most I can see is if Nintendo had worked out a specific deal with them and were involved directly with the localization.
As for the rest, ToD and ToE are from a point in time where they and many companies were just starting to localize RPGs, and weren't anywhere near as good as today. TotA cut out voice acting in skits, but those aren't the biggest deal and more importantly they've learned to remedy that with Vesperia. I'd like to see specific examples of ToL being poorly written, though I guess cutting out VA for all the postgame quests indicates they were kind of fucking around then.
Even though I'm defending them, it's not like I really consider Namco Bandai to be a great company in handling their games. Outside of the XSIII bullshit they've been improving over time with their series, but they've done some of the stupidest shit I've seen since the 32-bit generation started. Cutting out the story in AC3 is their real crowning achievement.
