Back in 2007, I published the first YouTube bypass of the Master Lock #175 (very common 4-digit code lock), using a paperclip.
After the video reached 1.5M views (over a couple years), the video was eventually demonetized (no official reason given). I suspect there was a similarly-frivolous DMCA / claim, but at that point in my life I didn't have any money (was worth negative) so I just accepted YouTube's ruling.
Eventually shut down the account, not wanting to help thieves bypass one of the most-common utility locks around — but definitely am in a position now where I understand that videos like mine and McNally's force manufacturers to actually improve their locks' securities/mechanisms.
It is lovely now to see that the tolerances on the #175 have been tightened enough that a paperclip no longer defeats the lock (at least non-destructively); but thin high-tensile picks still do the trick (of bypassing the lock) via the exact same mechanism.
Locks keep honest people honest, but to claim Master's products high security is inherently dishonest (e.g. in their advertising). Thievery is about ease of opportunity; if I were stealing from a jobsite with multiple lockboxes, the ones with Master locks would be attacked first (particularly wafer cylinders).
