For example, Userify (https://userify.com, cross-cloud ssh key management for teams, with a nifty color-coded dashboard so you can actually see who has what access) doesn't seem to have any screenshots anywhere.
Your question about whether I am the target market is an interesting point, but how does a screenshot (or lack) help in resolving that, and how does someone know if the target demo wants to see a screenshot?
For example, I mentioned Userify; how about another (much better) example of Ansible Tower/AWX? It's great to just see a screenshot of the dashboard: https://www.ansible.com/products/tower
This is an example of another great product that's much better marketed than Userify, IMO.
How do I know they don’t want to see a purple cow?
A significant portion of working as a marketer is understanding the needs and behavior of the target audience, making a decision based on that understanding, and then validating that decision. And hopefully iterating on that over time.
If results are better when there are no screenshots vs. when there are screenshots, why would I include screenshots? Because a couple opinionated randos on HN who will never pay for my product claim to like screenshots?
However, your argument would be more persuasive without that last sentence (especially because you don't know me; for all you know, I'm a dog![0])

If it is so consistent in the industry, I doubt it's by accident.
Couldn't it also be because many SaaS companies are better at tech than marketing?
Doesn't mean they're not the best at solving the problem though.
And the pricing is always very separated from the actual product descriptions. Try figuring out how much an instance with the right amount of RAM and CPU you need actually costs! Maybe that's intentional, though.
