Reddit, Twitter et all don't owe you anything. They do not make money via read-access API calls - they lose money. It's super simple...
Only a fool would build a business around a free service with no escape plan.
Twitter eliminated 3rd party clients, and now Twitter is estimated to be worth 1/3 of its acquisition price.
Lastly - Twitter's market price has nothing to do with it's profitability. That seems obvious, but apparently needs to be said here.
It's not profitable. That's why they're cutting to the bone and not even paying a lot of their bills.
They had to make an advertising exec the nominal CEO, because a lot of advertisers have fled the platform.

I wouldn't call that Apollo app's author a fool. My understanding is they were turning a profit from the app up to now. So, apparently, it was a nice business. It's just that their business model is about to stop working.
Well, that happens to other business too sometimes. They'll have to adapt somehow or come up with another business. Life as usual.
