Depends on if you're in the EU or not. In the EU, if either the company has
gone to the wall or the software will not work on your specific hardware, you
can (in some circumstances) reverse engineer the source to fix it. IANAL, but
looking at logs doesn't taint anyone - logs just tell you what messages have
been sent, nothing about the code etc.

That's always the choice. I know I've reverse engineered the odd scanner &
printer or three, released the source and nothing has happened (I even offered
it to the company who made the scanner!)
