Afaik the apps don't have to ask you, they could just request the OS-level permissions. They don't do that because if you reject the request at the OS level, they can't request it again, you have to go to the Settings app to enable it and it's harder to do. So apps prefer to just nag you again and again until you say you're ready.
2M units globally, so maybe generously 1M in the US (assuming you're from there but multiply by some factor proportional to your country's consumeristic tendencies), divided by the population is only something like a .3% rate of ownership. So not quite as prevalent as gopro, which has sold something like 35M in the US over the past 10 years [1]
The fiber is afaik a big factor for slowing rate and amount of sugar absorbed (amount because apparently some of it makes it far enough to feed gut bacteria in the large intestine).
The idea of some kind of universal fact is also misleading, some statements of fact are only statements of belief, others are so ill-defined that people end up debating two different things.
I think prediction markets (polymarket et al) get this right. Every question as vague as "is the earth warming" has resolution details which define some way to resolve the question such that all parties (even those with economic interest to disagree) have trouble disputing the outcome.
For a question like the earth warming, it would usually be something like "according to ___.org website on Y date", which in that case the final prediction becomes: will the average temperature in the period from 2016-2026 be greater than Y on ___.org, which is a bit different than the original but easier to arbitrate.
In case anyone else finds this interesting, the DOD has night vision goggles which have nearly-zero latency (all analog), amplify much better than digital cameras, and emit very little external light (hard to spot by adversaries).
Show us a link to a Facebook advertising API which can give me bidstream data which includes a user's demographic info? The links describe "Modern programmatic advertising" including "Patternz" but have not shown that Facebook is an implementor.
For the record every time I have advertised on both Google and Facebook, it works in reverse: I give them my ad, audience info, and how much I'm willing to bid, and they run an auction per impression (of which I don't get to participate in knowing the details directly). I get no user data, only the bill. If I did get user data (presumably with user consent) I would start my own direct-marketing mailing or email list and stop paying the ad-tech companies each time (who act as gate-keepers).
