The saying goes if you’re not the customer, you’re the product. Now, you’re both. Every big social media app is testing subscriptions. It's a business model that comes with a perverse incentive. Just like airlines, if you make life worse, more people will pay.
Everything is everything if you squint enough. You have to look past the meaning of the words and look at the context - social media is usually considered to be FB, Insta, TikTok, Xitter.
Ask ChatGPT if Reddit is a social media. It will give you answer “yes”, while noting features that are different from FB. ChatGPT is a good way to judge what is “usually” considered as this or that.
In global context, maybe. In this thread, not quite. I do not consider ChatGPT to be objective or that it understands context of an external source.
