Except it actually doesn't always do this but that doesn't suit your anti QF narrative. You only see the anytime points only where there are no CR awards on that date.
I just did this search

and look what comes up at the top of the list

but if i search a date with no CR availability then of course am only offered anytime awards. As stated previously easy to filter those out with another a button click, and then browse for availability.
Not a great interface but not the deliberate hiding of available CRs you are implying.
I dont think anyone here only has points in one program, that is a weird assumption to make on a FF site. But the reason I would not fly some of the airlines you choose or go to their home bases has zero to do with FF alliance. I personally have flown many non OW airlines outside of capital cities serviced by the core OW partners.
That said for those of us in full time work with limited time to do self funded travel each year, spreading your travel across too many programs leaves you without enough points in any of them to redeem anything useful.
Velocity does not have partners that cover as many destinations as OW, I collect Virgin points where offered but certainly dont go out of my way, as their schedule is limited outside of the capital cities. And IMO if you need to buy points, then just buy a ticket because you arent playing the game correctly.
When Ansett was still around they were my primary FFP and because they were a full member of Star Alliance and had many ways to earn points on top of fly Star Alliance it made sense. But I still also had QFF and a credit cards rewards program.
Rex can only earn points by flying Rex no airline earn or retail partners, so not viable unless you fly regionally very very regularly.
