Matter has nothing to do with Google except they are supporting the standard. If you care so much about an open ecosystem Google Home shouldn't even matter, you would be worried about Home Assistant support.
> NOTE for Android users: You need to follow the instructions at the bottom of the page to add the test device to the Google developer console, otherwise commissioning will fail.
Anyway, you absolutely should care about Google Home support if you want to sell a device. It'd be ridiculous to sell something that only works with Home Assistant even if I'd personally be perfectly happy with that.
Are you saying the home assistant docs are wrong? Please, elaborate.
> This process is a bit more involved but is also pretty straightforward and easy to do in most setups, though it is not officially supported and is intended for developer use.

I do not want another crappy USB C type experience to satisfy the zero dollar hobbyist. We'll just end up with zero dollar garbage from large manufacturers named Xhflk.
