Google's approach
> when Google announced that all users of its Nest smart home products, which it also bought in 2014 for $3.2bn, would henceforth have to login to their kit via Google accounts, giving the search engine monster access to all their physical whereabouts.
I can't let this pass without pointing out that Google actually fucked up worse than this.
They announced that you have to login to their kit via Google account. But the reality is, it needs to be a "free" account.
NEST won't accept Google Apps for Domains (or whatever the fuck it's called now - where the domain in your mail address is yours not theirs). The only reason I can see is that the terms of free Google accounts let them pillage your data much more than AfD accounts do.
If you want to share access to the device with someone else, that's now via Google Home rather than the NEST app (because they want to push for Home being one place for everything), which also won't accept an AfD account *unless* you go setting hunting and tick the box that allows them to keep and track your web history.
Never let it be said that Google can implement something simple without accidentally convoluting the hell out of it.
Facebook are perhaps the one company I'd trust even less, means Oculus is off the shopping list then.
