I like how they repeatedly pretend that third-party client apps don't need to exist and just dismiss that use case entirely. They REALLY want people using their crappy, manipulative, ad-infested official apps. Doubly funny because many features that were later baked into the platform itself first emerged in third-party apps. Like, you know, retweets, replies, all that kind of stuff.
That said, Twitter was amazing 10 years ago. That openness gave so many interesting opportunities. No one could've thought they'll be taking that away for the sake of earning all the money in the world.
@grishka Actually, Twitter isn't earning a significant part of the ad pie, Zuck openly laughts about this. It's peanuts. There were a couple of initiatives of userbases to buy Twitter free and turn it into a non-profit.
