Apple is not the only one doing this. Windows, depending on how its configured and the hardware in it, will keep WiFi and even Bluetooth devices connected even while "asleep".
Example: I go out to the park with my Windows laptop. I turn on the computer. I pair my headphones and hop on my phone's wifi tethering. I do some stuff. I close my laptop lid, the system goes to "sleep". My headphones still think they're connected. My phone still shows the laptop is a client. I walk around the park for an hour. My headphones are still connected, my laptop is still a client on the tethering. I sit down, I open my laptop, it wakes up, and it's still connected to everything.
There is some reason to the madness, at least for connected Bluetooth devices.
Some people only have a Bluetooth mouse and keyboard (no wired devices), so the computer must maintain a connection to those devices so a mouse or keyboard click will properly wake the computer. But even when my laptop is closed and in my bag, it will turn itself on if I touch a connected Bluetooth devices even though it has no external monitor connected, until the laptop is burning hot with a dead battery.
I would say that requiring an external monitor connected or having the laptop open should be a requirement for turning the laptop on, except that monitors often go into sleep mode that requires the computer to wake them up and wait, and then we have all kinds of weird dependencies and people get really mad when their computer doesn't turn on.
There are just too many contradictory ways that people use their computers now. All wired devices, all wireless devices, clamshell, open but only external monitors, external monitors and laptop monitors, wireless external monitors via Sidecar, only remote access, etc. Apple used to have a "Allow Bluetooth Devices to Wake this Computer" option that addresses this exact use case but it was removed in recent versions of MacOS.
Don't get me wrong, I don't mind this especially with my devices that handle connected standby fine. I'm happy the moment I open my laptop I'm connected and even things like ssh sessions and what not we're still connected the whole time and my headphones are immediately available.
It's only been a problem with problematic devices that cause it to fully wake and never go back to sleep. Disabling those devices in sleep usually solves this.
