I also wonder at the specific level of aggression and the tone of your comment which does not seem to be an appropriate response to that person's specific comment.
People such as you are describing and rightfully criticizing are knowingly taking advantage of that. Indeed it's how a lot of malware gets installed too.
The person you're responding to is pointing out that a lot of people at the surface level do only appear to care about the results. They put something into google translate, it works, they gets results they are pleased with, they don't put a lot of thought into the fact that the data is going to an external service. That's not an inaccurate description of how a lot of people use their computers these days. Look at how many people signed up for ChatGPT accounts and put the chatgpt app on their phones and talk to it all the time. That's the level of critical thinking a lot of non tech users have about their personal data.
The fact that people will click yes/agree/OK on almost anything is how Windows computers got Bonzi Buddy installed on them back in the day, and now it's continued into the cloud-everything era.
