Amazon makes a lot from Amazon ads in their own search results. Also Amazon prime. Microsoft from bing / Windows ads. Just in news/search they made over 10 billion. Microsoft / Amazon most the bulk of their money in the cloud.
Well that’s not quite correct. If you look at their most recent 10-K, Ads made up about 8% of Amazon’s revenue. The bulk of their revenue is still retail (online, physical and third party seller services) with AWS providing about 16%.
Microsoft’s largest segment is cloud, but it doesn’t quite provide the bulk. Their ads business is small compared to the rest.
Certainly killing advertising would hurt them, but I’m not seeing a mortal wound here, so I thought I was missing something when you lumped them in.
