I'm not inherently opposed to the publication of weird-and-interesting PC races (though I don't like them in MY campaign, and didn't in 3e either), I think there's a few differences this time around because of how 4e presents them.
1) Everything Is Core
In 3e, there was a pretty clear picture of what "default" D&D looked like, and it was also pretty clear that later supplements were not "on by default." The new policy changes this. It creates an assumption that supplements, particularly PHB2/3/4/12452, is "on by default." This makes it harder for DMs who want to run campaigns without the weird-and-interesting races, because, the be honest, the further ones game is from the default, the more specialized its audience and the harder it will be to find/retain/train new players.
2) Deliberate Spreading of Content
To compound the above issue, 4e has deliberately taken a policy of holding some "classic" content in reserve for later versions of the PHB/DMG/MM, in order to ensure more sales. However, this also creates complications for the DM. In 3e, a DM who only wanted the traditional basic races could just say "We're only using the PHB1." Now, that content is (deliberately) spread throughout several books, so the DM has to create a specific list of X and Y are allowed, but Z isn't. Again, this has the effect, at least psychologically, of removing the game further from the new "default D&D."

Resistor, you speak in FACTS.
It is much easier to add exotic flavors to a soup than it is to remove them once they are mixed in.
I'm sure there are players out there who balk when told they can't use everything in every book that's come out yet, but overall I think it's a bit exaggerated as a problem. I've played in several campaigns where the available options were limited, sometimes pretty sharply ("Only dwarves and gnomes are available as starting races," for example), and nobody complained.Query, because I would really like to know.
Is a DM saying race x,y and z and classes f and q are not present in this campaign setting really that much of a dealbreaker to people?
True, it also makes it more difficult to create a campaign world that is high quality.
