Recruiter: "Oh, I see you left your previous company soon after joining, what happened there?"

"They used Microsoft products, so I refused to touch the computers"

Depends. It's a factor. My previous employer was acquired by enormous American megacorp, and the first thing they started is forcing Microsoft infrastructure on us, a software development company that had Linux infra already in place. It immediately made all the work a bit more frustrating. Some people left because of that, and they were right to do so, things got way worse since then.
