I agree that some companies would not like it.
You can see a lot of pictures of crashed aircrafts here and I am shure that an involved company is also not happy about that!!!
But aviation is not just only about airliners!!!
And the the club "Ein Hansajet für Hamburg e.V." is quiet happy about a few pictures during the restauration (which I think is also maintenance) shown here like this:
I remember last year one engine of the Breitling-Conny was maintenend at Hamburg live in front of a few thousand aviation enthusiast with probably thousands of photos existing now! You can see some good ones even on facebook and the technichians are quiet happy about that!
I also remember a few years ago a big political discussion in Germany because of CIA
-flights in Europe with suspected terrorists. These flights were of course spotted by aircraftspotters with a lot of photos! And the CIA
was not happy about that! And it could be that some of this flights are also visile at this db!
And I know a lot of pilots who are not happy about beeing spotted at their work or hobby!
