I see a lot of misappropriation of terminology (in this case, "reactive") in libraries and documentation. But unfortunately this is something that has been going on for a long time and it's an impossible task to stop and, check and verify everything that is released.

However, if this is the case, then the criticism here against React shouldn't be that they're not reactive, but that they've used "reactive" wrong in their documentation.

Like other commentors, I also don't like the message in the slides and do not think that criticizing a competitor is a good form of marketing. But, I do think we should remember that it's hard to get the full context from slides and to not judge too quickly.
