Totally agree. It doesn't matter how well Ubuntu studio runs, it doesn't have the right apps. And likely never will. Wine is a non starter. And the stability of such a system is generally unproven as many vsts have no official Linux support. I'd love to try it if fl studio or reason or similar had a Linux port. Or Linux had an audio app that could compare; it doesn't. Until then, there's nothing compelling.
You're pretty much off the mark, on every single point:
1) Most Windows VST .DLL's run just fine, unless copy protected - and even then, iLok can be made to work. You won't have a Catalina-level catastrophe on your hands, either.
2) Apps: This is the entire point of Ubuntu Studio - once done with an installation, you have an amazing suite of apps to try out, without requiring further installation/sourcing. Multiple DAW apps are available: Ardour, Rosegarden, Bitwig Studio, QTractor, LMMS, Audacity, Renoise, Tracktion Waveform, ZRythm, Radium - and even REAPER (one of the best DAW's in existence) is Linux-native now.
3) FL Studio runs great under Wine and there is no reason not to run it that way. It is quite stable and has not crashed on me, ever, after years of use. LMMS is also a viable alternative to FL Studio too, also very stable.
4) Ardour is excellent, and so is Harrison Mixbus and XDubber.
There are many amazing new-generation apps which are available in Linux native versions, too - see for example VCVRack, which performs better on Linux than it does on my Windows DAW ..
You're completely missing the point. It's fine for amateur, non-live, non-critical work. But just because it works for you, it doesn't mean the software is stable. Hell, KDE itself (at least the kubuntu version) is not very stable so I doubt this version of ubuntu studio will be either. And suggesting to run VSTs on an unsupported OS or FL Studio under wine is likewise fine for amateur, non-live performance mode. For everything else, it's tempting fate especially when your desktop environment crashes when displaying the desktop number after switching desktops (one of many, many issues that cause kde to crash, lock up etc.).
The software is stable and I've used it professionally to track bands in a real studio for years - right alongside full-blown ProTools, REAPER, and now Luna systems, which have just as much failings as you seem to think would preclude professional use.
In fact the Linux DAW has saved my ass a few times - most recently with the catastrophe of Catalina nuking entire suites of apps and plugins that were needed for production.
FL Studio under wine: pro's can use it. Just because you don't like the technology doesn't mean its not professional - you just haven't bothered to get competent at it. As is demonstrated time and again in the pro audio world: its not the instrument, its the artist.
Ubuntu Studio is great for artists and anyone wanting to learn pro techniques, whether they are fashionable or otherwise, would be wise to give it a go - in spite of the naysayers who have gained no production experience with the tool because of their own prejudices...
