They killed Nest!? Nest did make some egregious mistakes, but still. The way Google is killing off stuff reminds me of Microsoft in the 90's touting, then killing APIs.

Google did not kill off nest. They killed the "works with nest" API and replaced it with "works with Google Assistant".

So then they are literally touting, then killing off APIs.

Your comment said they killed nest. That was incorrect.

Yes. I based that off of one of the tombstones I saw on one of the sites, but that was hyperbolic.
