The main character is ungrateful asshole, who has lots of people who support them, but they don't care about said people. I say it as a person who experinced grief of losing a loved one and who has close online friend with whom I have never met in person.
That twist with the bot was expected by me. I just thought that it would take darker turn, where the main character would learn about the twist only after deleting it, consequently deeply regretting it
