I would encourage you to re-think your comments. You just labelled some people "lazy or incompetent" while having barely any knowledge of the situation, or what resources they have or don't have available. Libraries aren't start ups focusing on scalability, their focus is on preserving knowledge and helping academics and the public find it.
If you believe that they should focus on the scalability required to handle bot traffic perhaps you would be best donating money to them to help give them the resources to be able to do that, or volunteering to try to help understand their problem and fix it if you believe that it's a skill issue.
Reframing what you said in a more positive way could be: - I wonder what architecture they used for this and how it could be improved? - I wonder what resource limits they have that prevent them from handling this issue? - I wonder whats unique to a library that limits their ability to do what tech companies do?
