Ask HN: Company asks to BYOD. Is it a red flag?

I recently got hired at an early stage YC startup. I was told to bring my own device for development. I haven't been able to find good information for this on Reddit/HN so wanted to make a post about it.

I was wondering if asking employees to bring their own devices was considered a red flag? It seems strange because they are already paying such a high salary that it doesn't make sense that they can't afford a machine for their developers.
