No, he hasn't been attacked just as much because he's a lot more level headed. He doesn't show how he feels about Superman Returns down people's throats and he isn't repetitive. Also he doesn't beleive that Man of Steel won't happen and Justice League of America will happen simply because he hated Superman Returns.
The fact is that we have no idea what will happen. Justice League of America could get made or it could completely fall apart. Man of Stell could get made or it could completely fall apart. Both might get made (though not in the same year obviously), and both might fall apart. We just don't know.
Technically, Man of Steel is farther in development than Justice League of America. It has a director officially announced who is free once Valkrye is done (He's no longer doing the Mayor of Castro Street). It has producers. It has the sets for the Daily Planet, the Kent Farm, New Krypton, and Metropolis which haven't been taken apart yet. It has a script, and if not, it's almost done. It has a cast (Brandon Routh, Kevin Spacey, Kate Bosworth, Sam Huntington, Frank Langella, and James Marsden).
However, Justice League of America is getting on the fast track. It too has a script. It has a director, even though it hasn't been announced. It has producers apparently. It preparing for casting and pre-production.
We also have to take a look at previous Warner Bros. projects such as Superman Lives, Batman vs. Superman, Batman: Year One, Superman: The New Movie, and Superman Flyby. All of these were in stages right at, more ahead, or just a little below where both these films are. They both can fall apart at any time.
