Even if it's true, the author has no way to know that for sure, and anecdotally I haven't seen it.
Most of the people that I know that are buying right now are doing so because for the first time in a while (unfortunately) Bitcoin is in a fairly stable state. There are no (serious) forks coming up, no massive scandals like a major exchange going under, the mempool is back to a reasonable size, and there are some really cool things on the horizon like lightning network, and even further out possibly schnorr signatures.
Coming from the past months of forks, infighting, contentious upgrades, and lots and lots of FUD, whenever I was asked about bitcoin I'd gladly talk their ear off about it, but would end with a warning that it's a very iffy time to be getting into things with how much was happening. Now it's starting to be in a state where I would feel comfortable introducing people into the space.
