I don't see anything in the posted picture from the booklet to indicate
they're actually bootleg recordings in the sense of someone sitting in
the audience with a recording device. It's possible, but it's equally
possible that a concert hall like Concertgebouw has equipment installed
to potentially record everything -- mikes not (immediately) visible.
That way, those performers that want to can record their recitals for
their own purposes (or explicitly forbid the hall to do anything of the
sort, as I'm sure Zimerman would :-).
As this URL (and the annual financial report, also available online)
also suggests, equipment for this is constantly present:
https://www.concertgebouw.nl/zakelijk/feest/techniek
I'd assume all you have to do is switch it on to get at least a
tolerable recording.
Maybe it produces recordings of lower quality than when the tv or radio
broadcasters come in to record a specific concert. Then again, the
difference (between high end professional equipment and smaller scale
equipment) is probably smaller than it was 40 years ago.
I suspect Riaskoff records everything (unless told not to) -- also to
produce those cd's they now routinely send to subscribers to the whole
series, containing a selected recital from the previous year.
