This is all in my own humble view, but:

Modern technology is complex and getting things mature
is a process.

There are design flaws like the Meltdown/Spectre
desaster other vendors struggle with also.

The OpenBSD folks do a good job in taking problems
serious when they become obvious, by emitting patches
and not hiding the problem.

The number and frequency of patches over time is not to
bad.

And once again, sorry for the delay..
