I hear ya.
I get 1-6 meetings in the same time slot, people don't care to check so I don't care to show.
I decide which meetings are important for actually moving stuff forward and screw the rest.

There's only ever one guy who complained to my boss...
I didn't show up for a meeting for a Friday 7pm, invite sent at like 4:58pm the same day for some inane and absolutely not urgent subject.
I saw that invite come in, chuckled, closed my laptop, went home and ignored it.

Later that night, the guy went nuts and CC'd everyone's bosses because he had wasted the full hour and obviously no one showed up to his meeting "even though I made sure to check everyone's calendar and everyone was available and you're all unprofessional".

I don't do emails notifications on phones as a rule unless you wanna pay my rate 24/7, but I had forgotten to do my time sheet so I was logged in doing that...

I dabble in a bit of passive aggressiveness in the face of corporate bullshit, so I finished my timesheet and hit propose new time... Sunday 3:21 am...
"Checked your calendar and it was available. Sorry for the inconvenience."
Closed my laptop and fucked off.

The guy went nuclear over several emails.
Sent a quick email to my boss "Just a heads-up, I think I angered someone by not attending their 7pm meeting they sent at 4:58pm and proposing an equally ridiculous time"

Never heard from the guy again and the next week he wasn't in the company AD anymore.

Probably went full tilt cookie monster in the coke jar or something.
