"So, I'll gladly take the odd annoyed pedestrian over a compromise in my safety."
That's why I think of these as the SUVs of bike lights. To hell with everybody else on the road; if they get blinded or hit, that's their problem.
It's not just annoying; it's compromising the safety of other cyclists on the road/path. There are many appropriate places for very high-output lights, but a well-used bike path--with cyclists approaching you and your blinding light--isn't one of them.
