Shame I had to vouch you, I agree with you. Arguably those insights are just used to train models and profit off you as well. To a lesser extent this information can be captured by paying API prices to any provider. So ultimately if your threat model has no tolerance for this you need to go fully local. Models that run on 24gb VRAM are...useable now, but will not have the capabilities of these hosted products. So depends where your values lie.
