Right. That wouldn't be particularly smart, even to someone who doesn't fully understand the ins and outs of tax/corporate law. Is it possible that perhaps they _do_ have their 501c3 designation and are just communicating it poorly?
Lack of positive confirmation that they are a 501c3 != positive confirmation that they are _not_ a 501c3
All 501c3 are publicly listed. They are not on the list. We have positive confirmation that they are not a 501c3, right now, nor have they ever been one.
The possibility suggested earlier was that they have applied but are not yet a 501c3. I lack positive confirmation that they have never attempted to become a 501c3.
Since it has been two years since they became a nonprofit, I think that implies they either have no intention of becoming a 501c3 or else tried to become one and failed because they did not meet the criteria. But technically it is possible that it is just delayed.
