I was going to avoid commenting, but I'll add this as an opposing viewpoint and explain my reasons why.
You asked for a one word answer - in general, no.
But the reasons - net neutrality is all all about open and equal access by all providers to all things. In general and at a high level, at least. Removing this essentially means that providers are free to adjust paths based on any number of economic factors. However, keep in mind that this is primarily "provider-based". The real aspect of this is will "WikiTree be affected" - absolutely not, unless they decide to pay providers to give them preferential treatment with one provider or another, which is extremely unlikely to happen.
Big players like Hulu and Netflix have already made implications that they would be willing to provide some compensation for setting their traffic up as preferential, which gives better options through those providers that choose the deal to stream television and movies. I get that.
However, this opens the market up for smaller providers, like the one I heard on the radio recently, who was happy to hear it would be repealed and flat out said that they have NO intention to change anything - in fact, they expected their customer base to grow as a result, which allows consumers to choose the carrier that benefits them most, increases competition with carriers so that prices should drop at least a little, and increase options on types of traffic and such that you may want to see go faster on the internet.
So I guess I'll be in the minority on this one, but I just don't see how this affects WikiTree at all.
