I could make the very same argument against CrowdStrike, which has been focusing on uncovering Russian cyber attacks. Also here's some "damning evidence", too:

“There’s a Balkanization of cyberspace that’s occurring, and companies need to choose which side they’re on,” said Dmitri Alperovich, co-founder of U.S. security firm CrowdStrike.

Sounds to me like they've "chosen a side", like you're implying Kaspersky has.
