A local pilot called me with a preflight issue of a propeller blade on

Some mechanics told him it was safe to fly home.

Anyone disagree?

This is normal (to a degree). McCauley calls it "Blade Shake", and is a
result of the fit of the blade root in to the hub bearing. Statically,
there will be some "slop" (up to 1/8" at the tip is acceptable), but
under rotational loads, this "slop" will disappear.

Happy Flying!
