Twitter is a single, centralised source where RSS is decentralised - everyone and his dog can provide a feed which can be followed by the world. No censorship, no dirty tricks with algorithms between you and your audience, no BigTech Beasts™ feeding on your data. In other words, RSS is clearly the superior solution both for source as well as subscribers. Twitter et al might not like this but... who cares?
Most people aren't going to be subscribing to things that break twitter's tos and if they do there is still push notifications and other platforms willing to platform that kind of content.
