I think it will depend on what the final forensic determination is regarding how SolarWinds' build process was compromised. If it was something they did wrong, that was against the rules, they're not going to look good. OTOH if it was something that "could happen to any company", i.e. they followed the rules and got hacked anyway, then they'll probably do okay, and the rules will take the hit, and get strengthened. The bad guys always have the advantage because they can always think of something you aren't defending against.
I can't predict which way it'll go, or maybe some third way....
