I personally find it causes a lot of confusion. Generally the term "reactive" has become very buzzwordy and meaningless if late. I think Meijer's talk just touches on the beginnings of it.
Constraint and logical systems like Bloom also qualify in dealing with change (the underlying meaning if "react"). The nice thing about FRP was that it went way beyond event streams, which is why Rx is so disappointing (which is just about event streams, react + Rx is sort of FRP).
I think my general feeling is that "there is no true reactive", but it's trendy to be responsive in that you have a system which behaves in soft or hard real time. There are a lot of components of such a system and lots of ways to organize it, but no clear feeling for which is best.
At the end of the day it always feels like fighting between general purpose programming languages. Nobody can win, everyone optimizes for different things, and broad terms are useless except for marketing.
