This is a tragedy, and it's great that people are trying to help in any way they can. However, building stuff on Twitter's platform seems like utter folly these days.

What's the alternative?

You need the database. It must scale and be reliable.

It must have proper UI.

People must be able to use it without prior learning.

Let's say you create a website from the scratch. You need to use some cloud database. You need to build a simple UI which will work with bad network. You have few hours to do that. You need not to go bankrupt because entire country suddenly will use your app.

Twitter is well known to everyone. Twitter has API which basically allows to use it as a simple database. Twitter is web scale and can handle the load. Twitter has solid battle tested website and apps. And everything is completely free.

IMO it's a unique proposition and nothing compares to it.

If you have enough time, you can build better specialized app, that's for sure.

Truthfully it was a bad idea when Jack Dorsey owned it too - now that Musk is in charge, it's a no-brainer.
