is there any place on sane web site to share scanner firmware?
E.g. for Mustek ScanExpress 1200 UB Plus I could share *SBfw.usb* (got

No. And for a good reason.
Most firmware files are extracted from the vendor's Windows and/or Mac
drivers. These drivers come with a license and unless that license
explicitly allows redistribution of the firmware file (without the rest
of the driver), redistributing it is bound to get you into legal
trouble.
In addition, the SANE Project's web site is published on servers
maintained by GitLab.com so we have to abide by their rules as well.
Naturally, GitLab.com doesn't want to get into legal trouble itself and
requires that you have permission to publish whatever you publish. If
you don't have that permission, you run a the risk of getting "kicked
out".
# I'm paraphrasing from memory.
I had a quick look at the page you mentioned and could not find any
mention of licenses for the various firmware files ...
Definitely going out on a limb there.
Hope this helps,
Thanks for your explanation.
Yes, it's a difficult subject with these licenses.
I would say, if one owns the hardware, he is automatically legal owner
of the firmware.
I'm afraid that's where you're wrong. At least in the general case. If
firmware files are needed by any SANE backend, it typically means that
it needs to be sent to the device before said device works. As soon as
you power the device off, whatever was sent to the device just sort of
"evaporates" and needs to be sent again.
This is different from firmware that is preloaded on the device when you
buy it and a SANE backend works without any firmware file.
If a firmware file came with a vendor provided driver, it is covered by
the license that came with the driver. You normally don't own anything
and just (barely) get the right to use it.
Hope this helps,
I know, that the firmware must be uploaded to the device on every usage.
By "owning" I mean, that I have the vendor driver. If for what ever reason I'm missing this driver,
I see no legal problem to use a copy of this driver, I get from elsewhere, because I have the license to use
it by owning the hardware. The only problem from my point of view is, if "elsewhere" is allowed to
share it to me, even if "elsewhere" has no license to use it, particularly if the vendor has no
support for re-shipping the driver.
