> Like, what does this guy even mean about the algorithm sorting his inbox? Legit what the fuck is he talking about?

Gmail has a feature that can break your inbox into a priority section and an everything else section. You have to put in some work to flag and unflag messages based on what you think is important. It's not perfect but with some training it's helpful.

Some people turn it on and expect it to read their minds about everything or think they can ignore the everything else section.

You can just turn it back off. You don't have to leave Gmail.

> And speaking of spam, I have a bunch of proton mail accounts and outlook accounts and iCloud mail accounts and Gmail’s spam filter is easily the best.

Agree. This person's reduced spam experience was due to the new e-mail address and being disciplined about not signing up for a million things on it, not because Proton is better.
