I'm not sure what that "sinking ship" means. That ship was sunk for us who paid lifetime updates. It's now resurrected as freeware which means the Sonar DAW is not removed from my system and archived. It would be interesting to see the amount of downloads when it become free. I've read on other forums where people downloaded the Bandlab version just to tinker with. When any article that comes up with freeware this will be the top one mentioned. You will never see a free DAW with this much features.
Sure some have left to test the waters and may not come back. Since it doesn't cost anything anymore it will always be there. I have too many DAWs as it is and keeping up is pricey. With FL and Bandlab I don't have to put any more money in them. DAWs like Live and Cubase can break deep into a small budget despite how great they are.
