I do not understand it... Why Canonical is hidden and don't
communicate with rest of world? Otherwise touchpads could
work out-of-box on non Ubuntu systems too with mainline
kernel.

It must be really frustrating for Ben and other people (me too)
who in last months working on ALPS patches to support that
touchpad as we know that Canonical already had some working code
for that touchpad...

Hi Pali,

The fix in the DKMS package you referenced was not written by
Canonical but by ALPS, as it came from them I think it is
reasonable they send it to upstream, isn't it? As you can see the
patch is non-trivial.

After we got the patch from ALPS, we had follow-up conversation a
few times with our contacts at Taiwan and asked if they would
upstream it, but unfortunately to no avail. I am as desperate as
you if the fix cannot land in mainline, which means many Linux
users will not benefit from it.  We also had opened this bug [1]
for this particular issue, there is nothing to hide. If there is
any code written by us, we happily submit them upstream.

Why couldn't you guys send it upstream yourselves?

For ALPS 73 03 28 touchpad it is probably too late now, see:

Because Canonical doesn't collaborate with the upstream
community in any meaninful way.  They've been a bad player
since day 1 and will always be.

This reminded me of this old thread [2]. How hard is it to run this
command in your kernel git tree?

    $ git log --pretty=oneline --author=canonical
