Only on HN will someone who makes money writing software complain that other fellow developers are asking for money from him for their software.
A service to clean up the UI does nothing to solve the issue at hand.
The complaint was about the summary, which Mimestream doesn't include.
"We are going to use your email to train our LLMs. I'm not okay with that... my confidential commercial information is NOT okay to use to train your models [...] So... goodbye Gmail."
The title is Bye Bye Gmail.
