Many of the companies under Bezos were acquired by Amazon, but Bezos himself acquired a handful under his investment arm, Bezos Expeditions. This is the complete list of Bezos and Amazon companies.
AbeBooks: Amazon acquired AbeBooks, founded in 1996, in 2008
Wait, what?
In 1998, Bezos was an angel investor in Google. His $250,000 investment’s value has ballooned to roughly $3 billion. This and his 2011 investment in then-startup Airbnb are some of his most prominent.
Double whaaaa?
Seriously, I had no idea that he's got his claws in everything. I guess I should have, he's a billionaire and all.
Nextdoor: Nextdoor was founded in 2008 with the goal of creating a way to interact virtually with neighbors. Bezos Expeditions was among the app’s investors in 2011, altogether amounting to $40.2 million in funding circa its 2012 evolution.
Business Insider: Jeff Bezos is an investor in business-and-general-news site Business Insider, founded in 2007. The 2014 investment round added $12 million in funds.
Ugh, iRobot too. So now I’ve got to replace my Ring doorbell and get rid of my expensive robot vacuum and mop. Damnit.
Oh well, I can vacuum and mop by hand.
Fortunately, our Alexa devices are gone, Audible has been cancelled, our Kindles have been replaced, Amazon Prime, Amazon Kids, and Amazon Prime Video subscriptions are cancelled, and I just got my old photos copied down from Amazon Photos yesterday. So, I think I’m good to delete my Amazon account altogether.
I didn’t see thriftbooks on the list, so that’s a relief.
Any video surveillance not controlled by you and you only seems like a bad idea. iRobots products have had privacy problems for years, regardless of whether they're owned by Amazon or not (which they aren't, merger got cancelled). Alexa does cost them money, but I wouldn't use any non-FOSS non-self-hosted smart home system for privacy and security reasons.
