> Russia has demonstrated that they can conduct so-called "hybrid warfare" as long as it doesn't lead to serious injury or death and the response will be meager

At a certain point, it stops being "hybrid warfare" and starts being "obnoxious prank".

Russia's deployed (small amounts of) WMDs offensively and has blown up/set fire to some military infrastructure on NATO soil. I'd call these things "hybrid warfare".

Making a grocery store file a claim with their insurance for unrefrigerated food is more along the lines of "dick move".
