Virtually every product and service with a website and social media presence? If you get banned from Google, your visibility online pretty much falls off a cliff and your sales will likely never recover. So anyone making money from a website is dependent on Google and other search engines... well mostly Google indexing said site.
Also, any business whose livelihood depends on a large company's platform. Businesses and entrepreneurs selling their work on Amazon and eBay, YouTubers and Twitch streamers making content for those platforms, influencers in general given their reliance on social media services...
Except for Google search+product combo, in every other example you cited there is a contractual relation between the product and the SM.
If I have a product page on Facebook, I have a contract with Facebook. Facebook could choose to end that contract with me and close my account. But Google News blocking/downranking a news site does not involve any contract ending between Google News and the news site. If I don't have a product page on Facebook, Facebook could still choose to block/downrank posts where users on their own free will mention my product. But I don't think this really happens at any significant scale yet.
Same applies your Amazon/Ebay/Youtube/Twitch examples.
