Sentry also did this by embracing the Business Source License. Technically, you can still get an MIT-licensed version, but it has to be more than two years old.
As a former employee that worked there during the days that Sentry really promoted itself being Open Source, it was disappointing to see. VC Funding and a growth obsession basically poisoned the well.
Honestly, this really resonated with me. Running an open source project on its own can be hard, running a popular one that gets used by tons of people and companies, while giving free labor, is extremely hard. Acting as free tech support to a large company, for nothing in return, is ass. Full stop.
I’ve seen some people make the statement that “maintainers owe you nothing”, and I’ve seen people state that “your supporters owe you nothing.”
While I believe there’s nothing wrong in a person willingly running a project on their own terms, just as there’s nothing wrong with refusing donations and doing the work out of some kind of passion… there’s only so many hours in the day, and developers need to feed themselves and pay rent.
I think a lot of people would love to be able to work on open source full-time. I’d devote all of my energy and focus to it, if I could. But, that’s a reality only for a privileged few, and many of them still have to make compromises. The CEO and founder of Mastodon, for example, makes a pittance compared to what a corporate junior developer makes.
