But I'm not so sure anymore. Truly, how many of us give consideration
about wake vorticies departing (or landing) behind larger aircraft?

Me. I often fly a piston single near lots of larger aircraft.

Remember, waiting isn't the only answer. You can lift off well before
the larger craft and turn into the wind ASAP. This can be a good reason
not to use an intersection departure. The big guy's wake will drop and
drift with the wind. Stiffer breezes clear WT faster, higher crosswind
angles help even more.

Same for landing... Stay above his (or her G) approach, land well
beyond the larger craft's touchdown point.

I don't guess at fault based on news reports.
