Rider is much better and faster than Visual Studio, and it's worth every penny. Making it free is a great move.
Just more Big Tech setting the terms for all of us trying to make a living.
This isn’t a new problem, but every time I see some form of “free” it gives me pause.
And Rider was built on IntelliJ and ReSharper, two products that successfully "competed with free" for many years before then.
So, if anything, I'd say that JetBrains is at worst reasonably well-positioned to survive dumping by larger competitors with more diverse product lines.
There are extensions like Roslynator which provide majority of refactorings at lower perf. cost, for free $$.
