I agree that a lot of subscriptions are really overpriced, but updates to an app are also a sort-of service. Pixelmator explained it quite well when their app switched to a subscription model, mentioning some fair (I think) pros and cons of the succession model, both from the perspective of users and developers.
Arstechnica runs on WordPress on AWS, and they have a really nice series of articles about it. Sure, you could use just one EC2 instance for everything, but on a high traffic website you would need a bit more.
Is this a long term source of revenue for Reddit? Or will it loose value at some point, simply because LLMs are all trained sufficiently on user generated content. Is there more to learn at some point?
Also it seems that a lot of content on Resdit is already AI generated, so it would train on data from other LLMs, which I’m sure doesn’t improve quality.
