To your point that AirBnB's and other global brands don't extend to most businesses, Facebook's recent outage provided such an experiment and indeed a lot of small businesses saw massive effects https://mashable.com/article/facebook-outage-small-business-...
Thank you for sharing this. Facebook received a lot of criticism for how they lobbied publicly against iOS14. Their reputation is ruined, and anything they say will always be taking with a cynical afterthought. But as much as it pains me to say it, they are 100% right in saying that iOS14 is indirectly going to create a lot of damage for SMBs and companies trying to disrupt the status quo. There's more nuance to it, but think of it this way: if your marketing budget plans on reaching 100m Americans each year, then the negative impact on micro targeting is not quite as bad since you're going for the mainstream customer anyway. But if you're trying to reach only 1m people, then losing micro targeting is a matter of life or death.
