Unless I'm misunderstanding the complaint (which is possible, it wasn't actually explained very well, just through an example or two but without a definition), it does help with the complaint.
Unless the complaint is actually "I like my services to have single word monikers", in which it doesn't, but in that case I'm not sure I think it's a complaint worth addressing without some explanation as to why that's actually important.
"Google now" is not memorable, and when used in various common sentences, the words are ambiguous. You could be talking about the company or the search engine. Similar for "Assistant", though a bit less so.
Whether it's a person's name or not, I know what Siri is. There are two word brands that work fine as well. Company <very common term> though, is hard to pull off.
