The excellent Linux Vendor Firmware Service project by @hughsie - LVFS, but which you might know through its tooling fwup and fwupdmgr - has published a "sustainability plan".
This basically asks larger hardware vendors to contribute engineering resource (people) or money, to help sustain it.
I rely on this superb project, as an amazingly convenient way of doing firmware updates to my ThinkPad using Linux.
