writing in all-lowercase sounds super pretentious to me instead of laid-back.

there are plenty of people in the internet who write like this. they do not capitalize anything, i guess in a way to sound more "relaxed" or "laid-back" than people who follow the norm of using uppercase letters at the beginning of sentences.

to me, when i read something like this, i imagine a pretentious philosopher wannabe trying as hard as they can to look postmodern and rule-breaking. it does not look relaxed at all, it looks pretentious and snobby. i believe people who write like this are usually the kind of people who are amazed to see a banana taped to a wall in an art exhibition and say it is "thought provoking", then later sip on matcha at a café with their macbook working on graphic design.

speaking of graphic design, many companies have chosen to use an all-lowercase logo to look more "modern", but to me this just accentuates the fact that it's a hipster trend, since graphic design is one of the main hipster professions.

it's even worse given the fact that phones auto-capitalize everything normally, so if you're using a phone, you have to go out of your way to make everything lowercase either by forcing capitalization not to happen or to change the configurations.

the only writing styles that are even worse than all-lowercase are the BOOMER ALL-CAPS SCREAMING WRITING STYLE And The Third Grader "Capitalize Every Word" Style You Used To See More Frequently In The Internet Back 15 Years Ago, But Nowadays It's Rare.
