If you’re a publisher only then RSS/Atom makes much more sense, especially if you want to retain ownership and control over content you created. If control is not important to you and you want to incorporate social aspect into your website (comments, reactions) then ActivityPub seems like a convenient way to go about it.

One thing that I strongly disagree with author of the blog post is the discoverability aspect. Yes, initial federation kind of sucks but at the same time your readers on Mastodon will be able to boost it and increase your reach.

Currently everything on the Internet is assumed to be free. Robots.txt is just a suggestion and not legally enforceable. I assume RSL is supposed to communicate terms of use explicitly, like a EULA.

Robots is just a suggestion and so is this because scaraper never cared about legality of things. All this thing does is make license more easily accessible but consequently, do we want to make it easy for them in the first place? Make scrapers work for it.

Reddit is astroturfed to hell, I prefer my posts to come from humans rather than companies trying to game system for financial benefit.

Web browsers are the most resource intensive apps these days. Dedicated app doesn’t have to run JavaScript or ask for UI elements over network so it’s better for both battery and bandwidth.
