We're huge fans of Sentry and have it deeply integrated in our products. The fully open source nature has helped us a ton with these advanced integrations, being able to look at the code to see exactly what is happening instead of relying on docs (which are great as well, not faulting them).

At the same time, I remember seeing a new startup that had completely ripped off Sentry + docs and had just done a find and replace for the company name. I thought I had read about it on HN but I can't find the link. It's clear we need a license that allows software to be developed in the open but prevents this type abuse.

I don't know if this license is the solution. It clearly isn't open source and should not be construed as such (they are very clear about this in the post), but I haven't seen other better proposals either. Armchair criticism is easy, and this seems like a reasonable middle-ground. We'll keep using Sentry and continue to be customers. Outside of their Sentry.io product, they have released and contributed to a ton of other Open Source libraries. As I understand it, that will continue. For me, this passes the sniff test.
