I think it's clear why you joined YC as it can be very beneficial to any company. The comment is questioning whether YC still remains to be a company focusing on the seed stage of investment. Nowadays it appears that a lot companies that go in have a business already in place and a significant amount of traction. This contrasts with YC's earlier companies in which many of them had only an idea or a prototype with no traction. Whether or not this is true I'm unsure of, but it definitely seems to be the overall perception of what YC has become.

I agree that there is a trend to accept some more later stage companies. While there are a few post seed companies, there are many in the batch that just started their company right before yc or a few months before, so that is still a theme. With a 100 companies every batch it is easier to have many more diverse companies represented.
