Nobody is forcing anything on anybody here so there's no need to end your thought with a defiant coda.

You misunderstand the objection I hinted at. Which is fine. I'm not pro-"marketing bullshit" because it's not an either/or choice. What I object to is taking a perfectly normal word someone uses and then choosing a narrow, fraught, medical interpretation of the word to ascribe to them a viewpoint of, essentially, "they want you to be mentally ill!"
I wouldn't wish "obsession" on anyone. It is extremely unpleasant and harmful to experience. Willingly giving your life to a company is not obsession, it's a choice.
