"Actually we’re approaching one year mark since the day when MSI stopped performing their obligations under Afterburner license agreement due to 'politic situation'."
MSI has no obligations to the developer according to international law. The country was sanctioned legally, following an illegal (according to the world: 143 countries voted to view it as suck, with only 5 (including Russia and Belarus) voting against) invasion of a sovereign state. The reason I'm mentioning it is not because of politics, but to point out that the developer uses the situation to spread pro-Russian propaganda.
As for MSI Afterburner's future, I'm sure there's plenty of talented programmers can be found elsewhere. I stopped using it years ago anyway.
I'm not sure how him saying he's not getting the information he needs to continue development, or being paid for that matter, qualifies as "spreading pro-Russian propaganda." Sounds like a statement of fact from his view, and moving to a new country isn't exactly an easy solution.
As for others being able to do this, I'm sure there are plenty of programmers that could
do it, including within MSI. But the benefit of MSI Afterburner was that it worked with just about any GPU (outside of Intel Arc and many integrated solutions). I don't need another Asus GPU Tweak clone, or ASRock OC Tuner, or Gigabyte Control Center, or EVGA Precision X1, or any other specialty variants that are bloated and only support graphics cards from one company. MSI Afterburner is lightweight and works at least as well as any of those others I just named.
I do wonder who actually owns the source code for this project. Sounds like some of it is MSI, but potentially a lot of it is the developer's own stuff and perhaps MSI doesn't even have all the code necessary.
