I recently had an experience kind of like this. I run a website about a kind of niche topic. I got a call from someone at a FAANG one day working in a similar space who wanted to chat about it. I get these calls pretty regularly and agreed, always happy to chat about it. While she was showing me some of what they were working on it started to look very familiar, and I realized that a lot of the ideas had been copied from my site. In some cases they had literally copy/pasted my content. I mentioned this to her and she got uncomfortable and admitted to something like "yeah we took a lot of inspiration from your work." Frankly I don't care that much, I put the info out there to be used and use it they did! But attribution (or an acquisition offer) would have been nice.
