Earlier quoted context omitted.
I can confirm. I work at a school with a massive fleet of Macs. The kids generally kill their devices with water by keeping their water bottle in the same bag as their MacBook. Doesn’t matter how often I tell them not to, they insist on doing this.
What do you expect them to do instead? Carry two bags? Keep the bottle in their hand at all times? I think both are highly inconvenient. There are backpacks with bottle holders on the outside, but in my experience, those aren’t very good at holding a bottle. Not bringing a bottle probably is the best option, but that may not be a good option in very hot climates.
How would you avoid water damage due to the scenario? Or do you consider it normal and unavoidable?
