Sorta. It’s not that they don’t conform to standards.
It’s that they don’t adopt new standards.
The newest iPhone still handles SMS and MMS the same way the iPhone 3G did back in 2008.
It’s like if Ford refused to add CD players to their cars and insisted you use their proprietary “Ford Media Disk”
And if you don’t like that, fine! It still has a tape player!
I used to work in a very very large well known hotel, ozone machines were only used to remove cigarette smells from guests who broke the rules.
And no one can be in the room while the ozone machine was running. They even had auto-shutoff timers so you could retrieve the machine after it had turned itself off and the room air was breathable again.
It takes several hours to run. This isn’t something you do to every room every time.
