Anecdotally, every startup I've been involved with for the last few years has completely embraced the WFH and used it to expand their hiring pools to the entire country. I've even seen some who are using tools like remote.com to hire staff outside the US.

I've also done a lot of interviewing over the last year and only one startup (Vanta) refused to allow long term remote. Every other company I talked to said they loved it.
