Yes many of the maintainers and key people are allowed to work remotely, but a lot more people work in the office.
I don't want to against the general WFH vibe, but that statement is hardly 100% true.
You don't get a paradime busting product without a tight co-located team
The current deficiencies in remote work will create opportunities for new products to fill those gaps.
I find it nonsensical for people to commute 1 hour only to sit in front of a computer that is connected to the Internet. And, lately, that computer happens to be the same you could use at home: a laptop, making it even more nonsensical.
Saturating streets with 5 seat cars with one occupant in them, cars that do not even need to be there anyways, creates a miserable urban experience for everyone.
Working from home also makes people focus on deliverables rather than superficial aspects of work: clothes, haircut, fitness, etc.
Plus, I don't think "I want to see face muscles moving" (something you can do using a camera anyways) is a proper justification for ruining the environment. The #1 challenge of the 21st century is how to make each human have a lower carbon footprint, and working from home fits well into that narrative.
Unless you seek a physical intimacy or violence with your coworkers I don't see the need for being in the same room.
