DisplayLink is dying due to high DDR prices. Dock companies are cancelling their display link portfolios due to the unfavorable economics.

Good riddance if this is how OSS is treated by synaptics.

Most recent thunderbolt docks and usb4 docks have good display support, and fallback to DisplayPort alt mode if the host does not support tbt4. Which is much better supported over type-c. Intel and AMD upstream host support.
