Buy a stock so that you keep holding it for 10 years is good advice, but not in the context of today's mania. It's advice that is supposed to mean 'buy safe things', not 'buy that thing with exponential growth that might be worth 1000x it's current value in 10 years.
I do think that blogs / advice like what this post does is overall a good idea and good advice. But I find it difficult to discuss in practice due to the HODL corruption.
