Not meant to be snide, no. It's something we thought about when allocating our budget: how are projects going to perceive this? Is giving $100 or $500 worse than giving nothing at all? So my question was also asked in earnest! :D

Back to your original question, then:

> Does $500 reflect the value and developer time savings you've received from the project over the years?

I guess the binary answer is yes, though I quite agree with you that it's difficult to gauge value in open source a priori.

Thanks for the kind words about Sentry ... and thanks for making Rollup! :)
