IFTTT has been sending emails to their users who make use of Pinboard integrations:
We’re working on a new IFTTT platform for developers that makes building Channels and Recipes a breeze.
Recently, we’ve worked with our partners to migrate to the improved platform, but some have chosen not to do so. Unfortunately, the Pinboard Channel did not migrate to the new platform and will be removed on April 4th.
If you received a PR-friendly email like this, you might think ‘Wow, the Pinboard developer is a jerk,’ and not understand the full context of what the “migration” entails. Pinboard creator Maciej Cegłowski:
IFTTT has already written all this shim code. They did it when they were small and had no money, so it’s difficult to believe they have to throw it away now that they have lots of staff and thirty million dollars.
Instead, sites that want to work with IFTTT will have to implement a private API that can change without warning.
This is a perfectly reasonable business decision. It is always smart to make other people do all the work.
However, cutting out sites that you have supported for years because they refuse to work for free is not very friendly to your oldest and most loyal users. And claiming that it’s the other party’s fault that you’re discontinuing service is a bit of a dick move.=
Cegłowski in a tweet from about a year and a half ago:
Right now the IFTTT business model is to charge one user $30M, rather than lots of users $2. The challenge will be with recurring payments
I suspect this is not unrelated.
