It's more of a comment on your previous response than a question.

1. Older companies tend to have wider footprint of real world use in various contexts thereby having a wider "body of work" for objective analysis and review.

2. There is switching cost when you get the 'thank you from the incredible journey" email or blogpost. So it is important to have companies that are self-sufficient and aren't at the risk of being acquired and shutdown which new companies are much more prone to.

PS: It is acknowledged that new companies most likely have fresher takes on old problems but you should also cater for their negatives enumerated above.
