Its another nail in the coffin.
I'd still warn that a lot of people will not switch to linux anytime soon. There is a lot of fear about "command line" (for example) even though some distros (mint, ubuntu, popos etc) are pretty much turn key.
If you can help a less technically savy family member or friend change that would already be a good movement. But a lot of people still rely on MSOffice products (for example)
Some additional options might be using a burner outlook account.
Or, if you need to run some windows apps, a VM is always an option.
