I know what you mean but I think this write-up is a bit too harsh. As
long as the goal is to get _as reliable as possible_ without spending
too much money, I think software RAID has its niche.
Besides, I've seen a few hardware RAID controllers having issues
themselves (and they weren't the cheapest ones available either).

I haven't seen this (luckily!). I do know that sometime in 5.x there
was a RAID-5 bug in gvinum but then again the whole vinum/gvinum
transition was pretty dodgy back then. This is why I waited until 6.x
to migrate.

I did. It worked.
