In reply to Chris Cree.

I’d say Jetpack was charging for their ability to integrate Twitter’s API into their offering and make it work for website owners and/or developers. Most people wouldn’t know what to do with the free API.

And I tend to think that the resulting posts, traffic and interaction resulting from tools like Jetpack’s would help Twitter – not take anything away from them.

My point was more like…. Jetpack didn’t see this coming?

That being said, even devs willing to pay were cut off. https://mashable.com/article/twitter-cuts-off-api-access-apps

Apparently there’s a LOT of buzz about this – and @TwitterDev is trying to do damage control – including promoting new Twitter API Free or Basic plans.
