The avalanche of reverse engineered/custom firmwares is definitely changing the synth landscape. I'm wondering how many other companies will start open sourcing. It isn't always trivial since sometimes there's proprietary software components or toolchains that can't be open sourced. But it's hard to imagine it won't be more common. There's a lot of mixed feelings in the community. A lot of musicians don't like AI, but they do want to have more features and bug fixes. A lot of synth makers are probably ambivalent too, especially if they have a stronger vision of what the synths should be that custom firmware ignore. Not to mention the commercial implications of adding features into existing synths, possibly making newer models less appealing. And of course people are copying UIs and workflows from other synths that took a lot of work to develop.
