> perplexed what the FANGs are even thinking in being so aggressive about pushing an end to WFH
I think the divide between WFH and return to the office boils down to something surprisingly simple: how much longer does your current lease last and/or how much office property do you own.
Companies that are about to have a lease expire, or are growing at a rate that they would need to soon lease an even larger building are going to be surprisingly friendly to WFH.
Companies that have 5+ years on their current lease and aren't planning rapid growth, or companies that spend enormous capital building mega-offices that they likely can't recoup the losses from unless people keep working in offices are going to be very resistant to wide spread WFH.
The company I currently work for has an office, is not giving it up (so I assume long term lease) but has nearly doubled since the pandemic. They are very WFH friendly. Another company I know had a shorter lease, shrunk considerably and is now too small for there old office: also WFH friendly.
I know a few other companies that aren't growing or shrinking and either own or long term lease several large offices in expensive cities. All of them are pushing a return to office.
Any company that owns commercial real estate is going to be very aggressive about a return to work, not just for their employees, but for everyone.
