Why would we be talking about model routers in the context of it being a conspiracy theory that OpenAI is ingesting data from users for training? Are you acting obtuse or do you genuinely not reading/following the conversation?
They are all very open about it. It's likely the reason why the frontier labs are ok paying many more dollars a person in compute than they receive as revenue on subscription users for now.
Especially if you're doing something in a very sparsely populated part of their latent space it just makes sense that it would get used. Their biggest problem getting solved at the moment is going beyond what common crawl enables.
If it's in the TOS, and your settings, and they have pages describing it, and it's the reason they're willing to subsidize your usage, and in your own words "they are all very open about it", then how exactly are they "stealing your work" here, which was the original point about this being a conspiracy theory?
Because most people assume that when they say "we will use your data to improve things" that it means "improve your experience" not "we will steal your non-public ideas and use our subsidised compute to scoop your work and say we did it for press releases and then conduct a weird flail of PR smokescreens and threats when the lie falls apart".
Its quite obviously about good/bad faith use of user data.
