I mean, we can be cynical about it, or we can acknowledge the fact that running a sustainable business around OSS is entrepreneurship on hard mode.

Yes, many companies start with good intentions which then change at some point, but there have also been companies that have managed to successfully balance both sides.

Grafana comes to mind, as well as ClickHouse, and TimescaleDB. I'm not as familiar with the latter two, but Grafana is certainly a good example. You can probably find some blemishes even on their record, but overall, I would say they have been excellent stewards of OSS. Especially considering the large amount of products they maintain.

So far, Typst seem to be on the right track as well, which is worthy of praise.
