I just played some desktop capture videos and fonts look totally awful with linear light downscaling.

I really don't think that looking at computer graphics is a good test for downscaling.
You should be using photographs or movies.
Something that was filmed instead of rendered.
With that, linear light downscaling should be better - at least if your display is properly calibrated.

The image scaled in linear light should look very close to the source, only lower resolution.
The image without linear light scaling is quite a bit darker than the source image, and finer details are lost.

So I shouldn't be downscaling in linear light if using Spline?

Catmull-Rom with the anti-ringing filter enabled is the only option which does not result in ugly ringing or aliasing artifacts when linear light scaling is enabled.
I don't recommend enabling the linear light scaling option with anything else.
An old example comparing Catmull-Rom and Lanczos.
