At first I thought people here were being pretty unsympathetic to an early version of a beneficial program. I could see a company setting a 6-month timeline initially, so they can reevaluate the program and choose how to evolve their support for open source. I expected to see something along the lines of, "at the end of the 6 months we'll evaluate whether to continue your free plan."

But no, they're quite explicit about this being nothing more than a way to try to get paid subscriptions from open source maintainers:

> Your complimentary subscription will expire at the end of the Benefit Period. After expiration, any existing subscription will continue unless you cancel. You may independently choose to purchase a paid Claude subscription at the then-current price through Anthropic’s standard signup process.

So anyone who participates in this will need to remember to opt out six months from now, or suddenly find themselves with invoices at the max 20x level.

That's pretty ugly.

Edit: I believe I misread the terms. As mwigdahl points out below: "If you have an existing subscription, it pauses while the free period is active. After that free period, your existing subscription resumes. As I read it, there is no "auto-subscribe" after the free period ends -- you just revert back to whatever you had before (or nothing, if you weren't a subscriber before)."
