I once got a “Karen’s reception” for complaining about a group implying they had 501c3 status (and actually saying as much in social media profiles which they started quietly removing after I got loud about it).
I was told “nobody cares about that” by a member of the media swooning a bit over this group. I was pretty annoyed because I consider 501 status as a mark of trust for donors and sponsors and it’s pretty sh***y disrespectful of the organizations that actually do the work to get it and the proper maintenance thereafter.
– I too had always thought there was a lot of administrative stuff involved so it’s not necessarily that easy (and the particular group in my anecdote would have difficulty filling out a mailing label).
