Even if it were accurate, it could entirely be explained by socioeconomic or demographic reasons — e.g. the majority of Gen-Z workers:

• live with their parents or room mates, thus no peace and quiet when WFH.
• are too poor to afford food, thus depend on the free coffee, cereal, and fruit to make ends meat.
• sample size is smaller, with most not working in roles where WFH is even an option (or is viewed negatively by superiors)
• the oldest of Gen-Z are still in their 20’s, and perhaps at the age where the desire to socialise in person is strongest.

Basically, the oligarch capitalist mouthpiece is throwing shit at the walls to see what sticks, because commercial real estate is fuck.
