Actually if you ask me, all you have to and really need to read is just that one line because it explains everything you need to know about it.
This alone tells us enough about what their vision was and would have been with Fallout. So it doesn't play any role if they love or don't love Fallout 3 as how it was done by Bethesda as they still would have always followed their own principle and design goals no matter what. - And they do, as how it has been seen by some of their projects.
You can still like something or even be proud about it and still decide against it because it is not your style or your way of doing things. Just as how the developers at Bethesda apparently love(ed) F1 and F2 a lot - their words - but decided to make F3 anything but First/Third Person and real time combat. I mean would it really change anything here if I dig up all the quotes and comments by Todd or Emil how much they praise F1, its design and the original developers? Not really. Because they still followed their own design principles in the end.
