I've seen Playstation commercials (basically sizzle reels) with Mass Effect along with Infinite Warfare and The Show.
If they didn't cared about the IP they would never put their resources to make another one. In every story there is always 2 versions, and to me this seems like a very complicated story that we will probably never know. But the facts are the current state of the game, the lack of marketing from EA that definitely looked like they didn't want to take any more risks with the game by injecting money to a big marketing campaign which would make their ROI even more difficult to achieve and also the fact that neither Microsoft or Sony decided to sign a marketing deal for the game which to me always felt weird.
To me the reaction to this by EA/Bioware will tell a lot of their commitment to the franchise in the long run, they need to turn this negative reaction and make a good lasting impression of the game. Keep patching it and improving it (even Deep Silver/Dambuster Studios made this for Homefront The Revolution, so they don't have any excuses not to keep working in the game) and also make all DLC free. Steps like that would at least make sure the biggest Mass Effect fans don't jump ship.
Not sure if that counts.
