For Discussion: If Macrobrewers are the Enemy, then why do Craft Brewers Copy Them?

There has been a lot of talk back and forth about those pesky macro-brewers pushing in on the turf of the craft brewers, and jumping on trends craft brewers have created. But, interestingly, there have been a few moves by the big guys that have actually started trends in beer making and beer drinking that the crafts jumped right on and followed.

The best example that I can think of is a style that has been around for a while: the Belgian White Ale or Belgian Wit. This has been made for years outside of the US, such as Blanche du Bruxelles by Brasserie Lefebvre (since 1983) and St Bernardus' Blanche. Hoegaarden's flagship is this style, which they claim was developed in 1445. These have managed to use wheat as an adjunct ingredient and perfected into the normally unfiltered, light and fluffy, strong yeast influenced flavor it has become.

Such crafts as Ommegang and Allagash have some pretty good versions of this. The White Rascal from Avery Brewing I enjoyed just last night had all the characteristics of the good ones, as many other crafts that also make one.

But can't we thank their popularity to Coors and Budweiser for their own versions, Blue Moon and Shock Top, which blew the lid off that style in America? If this is not the case then why does my local microbrewpub insist on an orange in mine when they are serving one of their own?

Is this just the craft brewers saying yes, those exist, but I can do it a lot better? here.
Or should they be thanking the macros for introducing these styles? Or, on the other hand, have these American breweries introduced these styles based on success in Belgium, ignoring Blue Moon here? Then explain why every micro everywhere has their own version of it, see list.

What are your thoughts? Can you think of any other styles that the Macro-brewers have made famous in America that craft brewers should recognize?
