A tale of centralization. Apple removes Tumblr from their App Store because, most likely, Tumblr allowed porn. (Why else would anyone use Tumblr these days?) Thenceforth, Tumblr desperately started to remove porn accounts from its site. Now Tumblrites are angry, and rightfully so. However, they fail to realize that by choosing a centralized service, they brought this upon themselves and it was bound to happen sooner or later. Especially poor decision if you run some kind of business or donation campaign through Tumblr. Yet few will learn the correct lesson here.
