You did, although I have no idea if OP is an affiliate of YC (IANAL but maybe you could argue the public API is a form of sublicensing the data?):

Given that the license is explicitly identified as both sublicensable and transferable and includes the right to distribute, I have a very hard time seeing how anyone could argue that the recipient of data that YC explicitly exposes through their "Official HN API" isn't allowed to use it.

My data is licensed only to Y Combinator and its affiliated companies (I would have prefer it to be licensed it only for news.ycombinator,com), not any other rando that can access it via a browser or an API

Sematic (OP's employer; rebranded to Airtrain?) is a YC company. Not a lawyer but I assume that would be included in "affiliated" since YC presumably has some ownership of them.
