Devices for avoiding VNE?

I don't know where you guys get these things from, but this behaviour means
these gliders should have their certifications cancelled.

I've never flown anything with these characteristics.

Maybe true if "near vertical", however, staying at a near vertical dive
is
something that requires a conscient effort.
The glider won't just stay there on its own.
To remain in a 90 degree vertical dive requires a significant amount of
forward stick force and concentration.
As speed increases, the nose will come up (away from vertical) even if
you
don't want it to, and even with full forward trim, it would still require
an
honest push on the stick to maintain that attitude.

Not true with all gliders. Several modern racing ships will, when trimmed
within CG limits for best climb performance, "tuck" or pitch down with
increasing airspeed, resulting in a large outside loop or exceeding VNE
without
pilot input. The crossover speed for this in my own ship is about 115
kts,
above which slight back pressure is needed to maintain speed.
