I would also like to read the source for the last claim of that statement. The break-in is well established in multiple sources, and also documented on Wikipedia (citing one of those sources). CNBC also add that they planted microphones (using phones) as listening devices.

"In the aftermath of the protests, Smith claimed that the protestors had blocked people out of the office, planted listening devices in the form of phones, and refused to leave until they were removed by police. " (https://www.cnbc.com/2025/08/28/microsoft-fires-two-employee...)

Protestors (in associated with the firing) also projected "Microsoft powers genocide" on the office wall (https://en.wikipedia.org/wiki/Microsoft).
