I have released some of my projects as Open Source, I also have a company with privative software.

Claude and AI partners have taken all what they could from the Open Source projects without giving credit or respecting the licenses. They have increased the traffic on websites in an absolute disrespectful way increasing the hosting cost in inefficient and ridiculous ways.

They have taken all the important books and not asked permission from the authors.

Fair enough. Fair use.

Of course I would create a competitor software to Claude or any others if I could. Using Claude(and others) of course.

I am not paying you 200 dollars/month for you to tell me that I could not create code that competes with you. If you try to go to court in Europe with this you will lose.

It is just the same fair use you proclaim for taking the data from others.

They would likely lose in the US too. But until that happens, they can keep living in their fantasy world...
