Something that I think is a bit misguided about this is that YC, at founding, was pretty unfashionable itself. The "accelerator" model wasn't particularly proven, and the thesis was that there was an untapped talent pool of "hackers" who just needed to figure out how to run a business and get connected to the right people/resources in order to be successful founders. Compared to other accelerator-type opportunities at the time (and some that still exist), YC was extremely founder friendly.

YC 1.0 made good on that vision — the success rate in the early batches is indicative of that. Once PG stepped back and handed the reigns over to Sam Altman, YC focused more on scaling up, while the startup ecosystem grew significantly as well, specifically around "Web 2.0". At the time, it wasn't particularly difficult to create a venture-backable web business if you had the technical skills and the right resources to achieve distribution. Along the same lines, being a startup founder became a viable alternative to becoming a banker or management consultant for high-achieving individuals. So naturally YC, as a backer of hyper-successful startups that generally have an easier time fundraising, became a magnet for the status-seeking subset of high-achieving individuals, leading to it becoming more of a stamp of prestige.

Since Sam Altman's tenure, it seems like a lot of the initial edge that YC had at founding is significantly diluted. There are a lot of aspiring founders seeking funding, but the Web 2.0 opportunity doesn't really exist anymore (at least not at the same scale). So today, YC looks much more like a large seed fund that funds more specialized businesses rather than the types of founders of the initial cohorts (i.e. hackers that want to build Web 2.0 businesses), and I think people are overly critical of that scale up. 2005 was a very specific point in time for the startup industry, and the YC thesis was not only well-timed, but extremely effective through ~2014 — but it's been difficult for them to figure out how to continue the momentum given changes in the ecosystem.
