I don't agree on the Blizzard stuff but in this instance I agree with what the US government is doing. Adobe is a stronger hold on the design tools market than any other company and Figma was good competition
What separates the two cases for you? Does it come down to there being more gaming companies compared to Microsoft than there are application-design companies compared to Adobe?
In my case at least it is just pure spite against blizzard
Just today they announced that they won't be funding SC2 esports anymore, and it is just yet another chip on their long defaced corporate image from my side of view
Not to mention Nintendo and Valve/Steam in the mix. Of all the issues that the video game industry has at the moment, a lack of platform competition isn't the issue.
