That was DAO. Modding has been a thing of the past for them since DA2. And especially now with Frostbite. Practically a different company. DAO was made right on the cusp of the EA buyout.
It actually seems to be more of a cost issue for Inquisition and for being on the Frostbite engine making modding problematic and not necessarily because of EA.
"Although Cameron Lee stated that they have “looked into” mod support, it may be too difficult to develop due to the Frostbite 3. “Dragon Age 3: Inquisition” is the first video game of the series to be built on the graphics engine, which was created by Digital Illusions Creative Entertainment.
Even with the challenge of implementing the feature, Cameron Lee left open a small possibility of mod support for “Dragon Age 3: Inquisition.” He also hinted that they want to streamline the modding process so that all of their fans, not just the hardcore developers, could use the tools."

Granted, this is from an early on interview, but I've read a few twitter threads where the Devs briefly mentioned that the mods were not entirely off the table, just that it wasn't very financially feasible to make it available to all fans and not just hardcore techies. I'm not tech savvy enough to be able to hunt through the threads on Twitter to find specifics, but if another mention comes up, I'll be sure to bookmark it. 
Even Mike Laidlaw who stated that they do not plan to support mods at this time, doesn't come out against them. He just states that he 'never underestimates the moxie of modders.'

EA, as a corporation, may or may not be against mods, I am unsure. I don't follow them and have not been inclined to research their habits to date. I do know that they had mods available from their community in their free marketplace, granted that most of them were just appearance, but still.
