You could have just ended your comment at:

Everything you said after that added confusion and this tangent instead of the conversation you wanted to have.

actively not choosing a product because of the lack of a feature seemed relevant enough to discussing said feature. the problem was that i forgot how weird online conversations are. i cant imagine a person in real life latching on to a small detail so strongly, ignoring basically everything i said.
