See Apollo as an example. You have a single dev, with very fine apple ios ecosystem knowledge, who always adds the latest apple api's and listens to community feedback and makes the best app, he alone can make in whatever way serves him to learn new coding skills and community requested features.
On the other hand on Reddit official app, you have tons of product managers forcing developers to work on many features that are outright against community feedback. See things like reducing information load, or making ads indistinguishable from content. Those features benefit reddit but many users hate them,
Apollo has dense vs wide posts and no ads. Official reddit app doesn't.
The value proposition and the audience they are catering too is very different. Buying the app is not gonna fix the fundamentally opposite goals of both apps. Reddit has fantastic devs, I can be 100% sure of that. it also wasted months of their time making some fake reddit nft side proyect that was dead on arrival.
