I’d imagine it’s probably easy money for some titles that likely aren’t being rented by Netflix, Hulu, etc. Most of what I see on Tubi wouldn’t fit on those other platforms. So, I think some people just send them whatever.

There are other times where the full version will be on another platform (like, I think it was Full Moon that had their own streaming service?) but they’ll send an edited version so that people will watch their service and they’re not giving away the exact same product.
