Why are these libraries not open source?

Can you provide a description of the list of functionalities that these libraries provide, so these closed source libraries can be replaced with open source implementations with community improvements?

From objdump I'm seeing:

filters/linux_x86_64/libFilterProcessor.so:
- depth_api_hole_filling_filter
- depth_api_horizontal_margin_filter
- depth_api_margin_filter
- depth_api_spatial_filter
- depth_api_temporal_filter

filters/linux_x86_64/libob_priv_filter.so:
- G2XL (Gemini 2 XL?) depth correction and decompress
- RVL/MT RVL/TC RVL/MTTC RVL compression: what is MT, TC, MTTC? 

frameprocessor/linux_x86_64/libob_frame_processor.so
- HardwareD2CProcessor: hardware depth to color alignment?

RVL compression seems to be useful for streaming depth images, but there is existing open source implementations https://github.com/catid/Zdepth, so it wouldn't be necessary to close source this.

I wouldn't care for open sourcing the firmware updater as it is highly hardware dependent. But the rest of these libraries seem to be standard image processing routines and there is huge room for community improvements, e.g. I can do many of these things faster with CUDA.

So, is it necessary to close source these?

Due to business considerations, it will not be open-sourced for the time being

Then this repo is not open source as advertised.
