There is now a modest obstacle -- Apple's walled-garden app store approach. The default settings of the very latest OS won't allow a novice user to run a crapware installer, and Apple's app store won't feature them (unless the harried reviewer glances away from his monitor to drink some water or something). HOWEVER, Mac OS X has never had this problem, and before the app store there was nothing inherently harder about writing crapware that bundles whatever creepy garbage could be monetized. So actually I really wonder why OS X and Linux never had this problem (to any major extent). Is it merely the awesomeness of single-digit market share? In that case, Ubuntu's safe but Apple better start worrying about it. Personally I suspect it's more complicated than that, but my ideas are half-baked.
