The campaign started at 2.5 million from day one which was raised back in 2019 in a separate fundraiser, probably to appear successful.

The rest I don't know. Seems like a very bad investment to make, perhaps people understand it as a form of donation/support (Purism does not look financially healthy).

But as the other commenter noted, these numbers aren't verified in any way.

Unless we can look at their books, it's just a claim.
