Ask HN: Was there a specific SaaS "clone" scandal for an open source project?

I'm working on a report which, among other things, talks about previously open-source projects that have relicensed under licenses like the Business Source License, which commonly forbid users from competing directly with the upstream developer's hosted services. Many of the developers of projects that have relicensed this way have said that they don't want to allow someone to clone their business by charging for hosting a database-as-a-service or similar, especially without contributing back. Was there a particular incident that made all of these people worry about this scenario? Have there been companies doing this that especially upset (e.g.) database developers? If you include other licenses with non-compete restrictions apart from BUSL, about 20 previously open-source projects have switched to include these. What's happened that most got them all concerned about this?
