Maybe I'm misunderstanding your comment but if you're under the presumption the Apple Developer membership is $100/mo then I wanted to clarify it's actually $100/yr for Apple Developer (it's actually 99 but I'm not going to play semantics).
Apple is $100 for a whole year, while Twitter is $100/month.
Aka Twitter is way overpriced by comparison.
That makes Twitter 12x more expensive. Wild.
