Yes, they are adding fees to the currently free APIs, the OP is not the currently free API, it's a paid API that has been around since 2017 and has always been expensive. There has been no announcement of what the new cost structure will be because that would require Elon Musk to plan more than a few days ahead
The first thing that stood our is that the table has a duplicate "Monthly Tweet cap" entry. Not enough people to review things before release?
This seems egregiously expensive for what you get. Who's the target demographic for this service? Does it really make sense in the appropriate industry?
One major reason to provide an API for a website like Twitter is to reduce the load from sloppy scraping and other actions people are going to do either way. This seems like a mistake.
