Sounds like the MS-PL which Microsoft used to use but switched to MIT. MS-PL is basically MIT but cover your butt against patent litigation.

You need to read the text more carefully -- the license terminates for any litigation against Supabase at all. Hypothetically, a former employee of Supabase suing them for some employee rights violation would no longer be allowed to use the software, which is not the case for any other OSI-approved license with patent shields.

The MS-PL has the fairly standard reactive patent shield that only activates for patent-related litigation for the specific software under the license and is kind of similar to the language in Apache 2.0, MPLv2, and GPLv3.

But they have now switched to Apache 2.0, so crisis averted.
