thanks for raining this important issue again

+1. I think that for GDAL the Help button should point to our doc (where
the links to the GDAL official docs are listed ). This allows us to
improve these algs with some more specific examples/pictures/etc

for all these 3rd part providers, we know that it is (and always will
be) difficult to keep the links updated to the official docs. I think
that, if we cannot provide this support, we should drop the Help button
for these providers. I know that it could sound harsh, but better than
opening a 404 page

A personal UI opinion: instead of opening an external browser, what
about resurrecting the old Help tab in the alg dialog?
