I'd fire any risk manager working for a tech company that is unaware cyber insurance exists.

The main issue I see here: cyber is already an established line. You would then need to add all optional coverages, exclusions, endorsements etc that the cyber line is currently offering to the gl policy as well. It would be hard (not impossible) and would make ISO gl worse than it already is. And BOP. And probably Marine... And any commercial auto (cars have computers, right?). It's just not worth it to extend those lines of business when you are offering an additional lob.

Having it as a separate line doesn't prevent an insurer from bundling the two lines, but it adds exceptional extra complexity to already complex lines.

Found this quote that kinda explains my perspective:

"If a company decides to rely on its GL policy to cover cyber losses the only certainty is that it will end up in a fight with its GL insurer"

Btw, I'm not an underwriter. I just used to program rating engines with ISO ERC data. I feel like I have a pretty decent grasp on how ISO decides to implement exclusions, so my comment was only to clarify from that perspective.
