Ask HN: Do SWEs harm themselves salary wise by not returning to the office?

FANG companies pay the highest salaries and have requested their employees to return onsite when the pandemic is over. Employees are protesting (e.g. employees wrote a letter to Apple execs). If working remotely becomes the norm, these companies will start to hire remotely. This will lead to lower salaries. You can already see that happening in the crypto space where companies are remote first most of the time and salaries are lower in general. So my question is, wouldn't it be smarter for SWEs to commit to come onsite for a couple of days per week to keep competition out? Do you already see it happening in your org?
