This is a Free Software antipattern. Yes, there are things that exist that claim to do the same thing as commercial software. No, that doesn't necessarily mean they're actually functional replacements for that software.

I mean some of them are, but there's no sampler that will painlessly play modern sample packs, no usable pitch correction, nothing a tenth as good at noise reduction / audio restoration as Izotope RX.

Also, maybe a violin is as good as a guitar, but you can't hand a guitarist a violin and expect them to be fine with that. Or vice versa, if you prefer.

I like, use and pay for Ardour, but I also like realism.
