Because finding acceptable and reliable players that will give the campaign a shot grew progressively harder as WotC released more and more splatbooks with even more powerful magic and more powerful classes, broken feats, and the like. They won't even give a low magic campaign a shot unless they're allowed to play whatever class they want, regardless if it fits into the campaign. WotC made it harder for dm's to run campaigns their way, with the increasing amount of player entitlement they put into their books.
If the people you game with won't play unless they get their way - maybe you should consider not gaming with them? Or maybe you should consider offering them something else?
You, as the DM, have the right to make house rules. This is an absolute given for me. If the players don't want to play by your rules, they can say. You are under no obligation to accept players in your games.
However, WotC are under no obligation to provide materials for YOUR style of gaming. They are trying to produce a game that sells, and that is enjoyable to play. If it doesn't suit your tastes, that doesn't make it wrong or badly designed - it simply doesn't suit your tastes.
As has been noted, the previews have bent over backwards to part-explain why low-magic is easier to work with - the math is laid clear. In your Wizard hunter game, you can keep the magic items out of the players hand, include the +1/5 levels to their attack, damage and defences, and with little other modification they'll be fine to fight level appropriate monsters.

It makes DM's out to be the badguy when the DM is forced to say no to that kind of crap. WotC should have went with a more conservative approach to elements of the rulebooks that can drastically alter the tone/genre of a campaign setting.
You keep saying this and I'll keep disagreeing with you.
A DM who wants to play a certain way is not a badguy - if the players don't like the style of the DM they shouldn't play in that game, and if the DM doesn't enjoy running games for the group then they shouldn't.
You seem to be blaming your problems with your players on WotC's decisions. You always have the choice of what style of game you run, with what players. Anything WotC does is seperate from that.
