Obviously this is a good thing that we want to see more of. I like the approach of asking engineers what projects to support. My first thought was that this doesn't seem like a large amount. Maybe we need a thread listing large SAAS companies that have donated nothing to OSS projects, though.
I'd love to see other companies express their open source donations in terms we can compare across companies. Yes, in absolute terms $155k (rounding up ;) is not that much, but Sentry is not that big. We have ~75 engineers. How much do other companies with 750 or 7,500 engineers donate to open source, per engineer?
