The $1500 goal was just reached on HDRI Haven's Patreon page, which was to unlock the last of the Vaults containing all of my previously for-sale HDRIs.
All 60 of them are now available completely for free in full 16k resolution under public domain.
Many of them also include a set of backplates, which are also free. There is no sign-up or email form of any kind, you can download what you need immediately with no restrictions.
I can't even describe how it feels to finally have all my work out there for everyone to use <3
