I know 1 who did, others did not and even if they download or buy the PHB to better understand classes, they were getting everything else as well. Certainly no one cared to get SCAG but this builder gave them all of the options that were in it. Before the c&d they would have also gained all of the subclasses and spells in Xanathar's. As much as it sucks to lose this excellent resource, I agree with WotC's decision.
I'm fine with WOTC's decision. It's their product and they can manage it the way they'd like. What I'm infering is that people are going to do right or do wrong regardless of the rules so punishing the 95% that do the right thing because of the 5% that are never going to follow the rules just kinda sucks.
