Fair, if your content is your product, but I’m more than happy for every LLM on the planet to summarize my page and hype the virtues of my product to its user.
Enjoy the brief window of LLMs "hyping the virtues of your product" to its users for free. In 2030 that's not going to sound realistic at all. And I feel I'm being generous pushing it up to 2030, the first "sponsored training data" either already exists or will probably be out this year, the only question being whether it will be publicly admitted to or not.
If there's no product, and it's free, why would one care about it appearing in the output of an LLM? If it's so secret that it shouldn't, then perhaps it should be behind some auth anyway.
Because writing is, in many senses, exposing yourself, and at the very least you want the recognition for it (even if only in the form of a visit to the website, and maybe the interactions that can follow)? Maybe you want at least the prestige that comes with writing good content that took a lot of time to create. Maybe because you want to participate in a community with your stuff. Maybe other million reasons.
I know that medium, substack and the other "publication" platforms (like LinkedIn) are trying to commodify even the act of writing into purely a form or marketing (either for a product, or for your personal brand), but not everyone gave up just yet.
Not everything everyone does is for a profit motive. I'm not trying to sell you anything ; myself included, when you visit my site. It's just reading material.
