Here’s the problem - it’s the same problem in many areas where AI is put to (ab)use:
I already have my own AI accounts. Several of them, really. Some of them paid. For work and for personal. If I want any kind of take from AI, which is in fact a very frequent occurrence, I can just prompt for one. For free even! And with my choice of model based on how important or complex the topic. There is zero value-add for me when some product decides to squirt an extra helping of AI somewhere it wasn’t needed. Summary of a long piece of text (while still giving access to the unabridged text)? Probably fine. An AI answer to a question someone else posted on a forum? Or injected above my web search results (looking right at you, Google)? No thanks!
I'm not sure you have explained the problem. You have explained why PhysicsForum might not appeal to you, but it doesn't have to appeal to you. It is not a problem if it doesn't appeal to you. It never appealed to most people.
