I agree with you, even if you are downvoted. I've wrecked more in-ear buds by (non-replaceable) broken cable than i can count, while i'm on my 3rd bluetooth headphone in about 10 years - i lost none of them, and the second one is still around as backup.
The security is a thing that can be patched if it pops up and is only an issue if your OPSEC differs strongly from the common citizen, and the energy argument comes across like a purity test - the light in my fridge probably uses more energy.
I would never go back to cable, especially since noise cancelling doesn't work without a battery anyway - and i am very unhappy without noise cancelling.
Also, i have a power bank where i can use 21600 Li-ion Battery cells as power source (and it doubles as charger for those cells) - on travels i take a few batteries with me, and even if i find myself for weeks without power, i will have it whenever i need it.
I don't know what VPN you use, but i have zero issues running Proton VPN and accessing catbox. Maybe some VPN nodes are used to attack Catbox and they are temp banned?
