I don't think going commercial has been that impactful. It sucks, it betrays the spirit of open source but whatever. A few examples:
reply- FluentAssertions had no moat, and it has been forked as AwesomeAssertions. Not sure what the author's play was here.
- Moq lost trust - we have NSubstitute
- AutoMapper and MediatR have been widely misused anyway
- Maybe MassTransit is a real bummer?
Switching to the forks/alternatives is still time and effort, often a lot of it.
reply> How large a project do you typically use dotnet for?
replyThe largest dotnet project I am responsible for has around 50 megabytes of source files sitting on its main branch right now. If you include the generated WCF references it's probably closer to 100 megabytes.
