Lies, damned lies, EOL projections
I once upset the finance department by making improvements to the billing system - as by doing so, I was extending the projected time-to-collapse and hence undercutting their case for a shiny new billing system.
Still, I got the last laugh. When I left two years later, the old billing system was still merrily chugging away, and it took over two more years (and a *lot* of effort) to get the new system even vaguely fit for purpose. So it was a good job that I'd been fixing and improving things despite their disapproval!
