Last time I played around with React Native was probably around when it first launched, there was no Expo then, and I haven't used React Native since so I don't even know what Expo is.
But another commentator wrote "yet another SaaS with questionable payment tiers" about Expo (https://news.ycombinator.com/item?id=41937886) which makes me already not want to use it if I ever touch React Native again. Not sure why a SaaS would be involved at all in this process.
You don't have to use Expo's SaaS to use Expo. Expo framework is 100% FOSS. However Expo Application Services is a really great SaaS product for doing things like cloud builds and Over-The-Air updates.
The anti expo sentiment is almost all based on the old days where you had to eject to use native dependencies. Expo is amazing now.
